'Covenant' in the Bible

And they set forward from the mount of Jehovah three days journey; and the ark of the covenant of Jehovah 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 Jehovah, and Moses, departed not out of the camp.

All the heave-offerings of the holy things, which the children of Israel offer unto Jehovah, have I given thee, and thy sons and thy daughters with thee, as a portion for ever: it is a covenant of salt for ever before Jehovah unto thee and to thy seed with thee.

Wherefore say, Behold, I give unto him my covenant of peace:

and it shall be unto 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.
