'Relieve' in the Bible

And he called his name Noah, saying, "This one {shall relieve us} from our work, and from the hard labor of our hands, from the ground which Yahweh had cursed.

"And there shall be for you a designated place outside the camp; {and you shall go there to relieve yourself},

and a digging tool shall [be included] in addition to your [other] utensils for yourself; {and then} {when you relieve yourself} outside [the camp] you shall dig with it, and [then] you shall turn, and you shall cover your excrement.

He came to the sheep pens beside the road, and a cave [was] there. Then Saul went in {to relieve himself}. Now David and his men [were] sitting in the innermost part of the cave.
