'Salt' in the Bible

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."

then your south quarter shall be from the wilderness of Zin along by the side of Edom, and your south border shall be from the end of the Salt Sea eastward;

and the border shall go down to the Jordan, and the goings out of it shall be at the Salt Sea. This shall be your land according to its borders around it.'"
