Scriptural mandate
Ezekiel 11:15-18
15 Son of man, thy brethren, even thy brethren, the men of thy kindred, and all the house of Israel wholly, are they unto whom the inhabitants of Jerusalem have said, Get you far from the Lord: unto us is this land given in possession.
16 Therefore say, Thus saith the Lord God; Although I have cast them far off among the heathen, and although I have scattered them among the countries, yet will I be to them as a little sanctuary in the countries where they shall come.
17 Therefore say, Thus saith the Lord God; I will even gather you from the people, and assemble you out of the countries where ye have been scattered, and I will give you the land of Israel.
18 And they shall come thither, and they shall take away all the detestable things thereof and all the abominations thereof from thence.
Ezekiel 36:23-28
23 And I will sanctify my great name, which was profaned among the heathen, which ye have profaned in the midst of them; and the heathen shall know that I am the Lord, saith the Lord God, when I shall be sanctified in you before their eyes.
24 For I will take you from among the heathen, and gather you out of all countries, and will bring you into your own land.
25 Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you.
26 A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
27 And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
28 And ye shall dwell in the land that I gave to your fathers; and ye shall be my people, and I will be your God.
Jeremiah 16:14-16
14 Therefore, behold, the days come, saith the Lord, that it shall no more be said, The Lord liveth, that brought up the children of Israel out of the land of Egypt;
15 But, The Lord liveth, that brought up the children of Israel from the land of the North, and from all the lands whither he had driven them: and I will bring them again into their land that I gave unto their fathers.
16 Behold, I will send for many fishers, saith the Lord, and they shall fish them; and after will I send for many hunters, and they shall hunt them from every mountain, and from every hill, and out of the holes of the rocks.
Isaiah 10:20-22
20 And it shall come to pass in that day, that the remnant of Israel, and such as are escaped of the house of Jacob, shall no more again stay upon him that smote them; but shall stay upon the Lord, the Holy One of Israel, in truth.
21 The remnant shall return, even the remnant of Jacob, unto the mighty God.
22 For though thy people Israel be as the sand of the sea, yet a remnant of them shall return: the consumption decreed shall overflow with righteousness.
Deuteronomy 10:17-19
17 For the Lord your God is God of gods, and Lord of lords, a great God, a mighty, and a terrible, which regardeth not persons, nor taketh reward:
18 He doth execute the judgment of the fatherless and widow, and loveth the stranger, in giving him food and raiment.
19 Love ye therefore the stranger: for ye were strangers in the land of Egypt.
Ezekiel 20:40-44
40 For in mine holy mountain, in the mountain of the height of Israel, saith the Lord God, there shall all the house of Israel, all of them in the land, serve me: there will I accept them, and there will I require your offerings, and the first fruits of your oblations, with all your holy things.
41 I will accept you with your sweet savour, when I bring you out from the people, and gather you out of the countries wherein ye have been scattered; and I will be sanctified in you before the heathen.
42 And ye shall know that I am the Lord, when I shall bring you into the land of Israel, into the country for the which I lifted up mine hand to give it to your fathers.
43 And there shall ye remember your ways, and all your doings, wherein ye have been defiled; and ye shall lothe yourselves in your own sight for all your evils that ye have committed.
44 And ye shall know that I am the Lord when I have wrought with you for my name’s sake, not according to your wicked ways, nor according to your corrupt doings, O ye house of Israel, saith the Lord God.
Jeremiah 11:6-11
6 Then the Lord said unto me, Proclaim all these words in the cities of Judah, and in the streets of Jerusalem, saying, Hear ye the words of this covenant, and do them.
7 For I earnestly protested unto your fathers in the day that I brought them up out of the land of Egypt, even unto this day, rising early and protesting, saying, Obey my voice.
8 Yet they obeyed not, nor inclined their ear, but walked every one in the imagination of their evil heart: therefore I will bring upon them all the words of this covenant, which I commanded them to do: but they did them not.
9 And the Lord said unto me, A conspiracy is found among the men of Judah, and among the inhabitants of Jerusalem.
10 They are turned back to the iniquities of their forefathers, which refused to hear my words; and they went after other gods to serve them: the house of Israel and the house of Judah have broken my covenant which I made with their fathers.
11 Therefore thus saith the Lord, Behold, I will bring evil upon them, which they shall not be able to escape; and though they shall cry unto me, I will not hearken unto them.
Jeremiah 23:5-8
Behold, the days come, saith the Lord, that I will raise unto David a righteous Branch, and a King shall reign and prosper, and shall execute judgment and justice in the earth.
6 In his days Judah shall be saved, and Israel shall dwell safely: and this is his name whereby he shall be called, The Lord Our Righteousness.
7 Therefore, behold, the days come, saith the Lord, that they shall no more say, The Lord liveth, which brought up the children of Israel out of the land of Egypt;
8 But, The Lord liveth, which brought up and which led the seed of the house of Israel out of the North country, and from all countries whither I had driven them; and they shall dwell in their own land.
Isaiah 14: 1-2
1 For the Lord will have mercy on Jacob, and will choose Israel and set them in their own land: and the strangers stranger shall be joined with them, and they shall cleave to the house of Jacob.
2 And the people shall take them, and bring them to their place: and the house of Israel shall poses them in the land of the Lord for servants and handmaids: and they shall take them captives, whose captives; they were and they shall rule over their oppressors.
Deuteronomy 27:19
19 Cursed be he that perverteth the judgment of the stranger, fatherless, and widow. And all the people shall say, Amen.
