'Single' in the Bible

So Samuel took a single {nursing lamb} and sacrificed [it] as a whole burnt offering to Yahweh. Then Samuel cried out to Yahweh on behalf of Israel, and Yahweh answered him.

So Samuel took a single stone and put [it] between Mizpah and Shen, and he named it Ebenezer and said, "Up to here Yahweh has helped us."

And so then, do not let my blood fall to the ground {away from} the presence of Yahweh, for the king of Israel has gone out to seek a single flea, as one hunts a partridge in the mountains."
