'Congregation of Israel' in the Bible

Speak to all the congregation of Israel, saying, ‘On the tenth of this month they are each one to take a lamb for themselves, according to their fathers’ households, a lamb for each household.

You shall keep it until the fourteenth day of the same month, then the whole assembly of the congregation of Israel is to kill it at twilight.

Seven days there shall be no leaven found in your houses; for whoever eats what is leavened, that person shall be cut off from the congregation of Israel, whether he is an alien or a native of the land.

All the congregation of Israel are to celebrate this.
