'Congregation of Israel' in the Bible

does it seem but a small thing to you that the God of Israel has separated you from the congregation of Israel, to bring you near to Himself, to do the service of the tabernacle of the Lord, and to stand before the congregation to minister to them;

Then one of the Israelites came and presented to his relatives a Midianite woman, in the sight of Moses and the whole congregation of the Israelites, while they were weeping [over God’s judgment] at the doorway of the Tent of Meeting (tabernacle).

the land which the Lord conquered before the congregation of Israel, is a land [suitable] for livestock, and your servants have [very large herds of] livestock.”
