'Covenant' in the Bible

They set forward from the Mount of Yahweh three days' journey. The ark of the covenant of Yahweh went before them three days' journey, to seek out a resting place for them.

But they presumed to go up to the top of the mountain: nevertheless the ark of the covenant of Yahweh, and Moses, didn't depart out of the camp.

All the wave offerings of the holy things, which the children of Israel offer to Yahweh, have I given you, and your sons and your daughters with you, as a portion forever: it is a covenant of salt forever before Yahweh to you and to your seed with you."

Therefore say, 'Behold, I give to him my covenant of peace:

and it shall be to him, and to his seed after him, the covenant of an everlasting priesthood; because he was jealous for his God, and made atonement for the children of Israel.'"
