Ezra 6:21

21 And the sons of Israel ate, that turned again from the transmigration, and each man ate, that had separated himself from all the defouling of heathen men of the land, for to seek the Lord God of Israel. (And then the Israelites, who had returned from the captivity, and also each man who had separated himself from all the defiling of the heathen of the land, to seek the Lord God of Israel, ate the Passover.)

Ezra 6:21 Meaning and Commentary

Ezra 6:21

And the children of Israel, which were come again out of
captivity
The tribes of Judah and Benjamin, with some of the ten tribes mixed with them:

and all such as had separated themselves unto them, from the filthiness
of the Heathen of the land, to seek the Lord God of Israel, did eat;
such of the Gentiles in the dominions of Babylon, and came with the Jews from thence, who were enlightened into the knowledge and worship of the true God, and not only renounced their idolatry, here called filthiness, but were circumcised, and embraced the religion of the Jews, and so were proselytes of righteousness, as they call them; or otherwise they would not have been allowed to eat of the passover, as they did, ( Exodus 12:48 ) .

Ezra 6:21 In-Context

19 And the sons of (the) transmigration made pask, in the fourteenth day of the first month. (And the sons of the captivity kept, or observed, the Passover on the fourteen day of the first month.)

20 For the priests and deacons as one man were cleansed, all they were (made) clean to offer pask to all the sons of (the) transmigration, and to their brethren (the) priests, and to themselves. (For all the priests and the Levites cleansed themselves, yea, they were all purified, and then they killed the Passover lamb for all the sons of the captivity, and for their fellow priests, and for themselves.)

21 And the sons of Israel ate, that turned again from the transmigration, and each man ate, that had separated himself from all the defouling of heathen men of the land, for to seek the Lord God of Israel. (And then the Israelites, who had returned from the captivity, and also each man who had separated himself from all the defiling of the heathen of the land, to seek the Lord God of Israel, ate the Passover.)

22 And they made the solemnity of therf loaves seven days in gladness (And they kept the Feast of Unleavened Bread for seven days with great joy); for the Lord had made them glad, and had turned the heart of the king of Assur to them, (so) that he would help their hands in the work of the house of the Lord God of Israel.
