Nehemiah 13:3

And the seed of Israel separated themselves from all strangers, and stood and confessed their sins, and the iniquities of their fathers.

And a mixed multitude went up also with them; and flocks, and herds, even very much cattle.

And the rest of the people, the priests, the Levites, the porters, the singers, the Nethinims, and all they that had separated themselves from the people of the lands unto the law of God, their wives, their sons, and their daughters, every one having knowledge, and having understanding;

And the mixt multitude that was among them fell a lusting: and the children of Israel also wept again, and said, Who shall give us flesh to eat?

Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.

Wherewithal shall a young man cleanse his way? by taking heed thereto according to thy word.

Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.

For the commandment is a lamp; and the law is light; and reproofs of instruction are the way of life:

Thy word have I hid in mine heart, that I might not sin against thee.

Now therefore make confession unto the LORD God of your fathers, and do his pleasure: and separate yourselves from the people of the land, and from the strange wives.
