'Number' in the Bible

The remnant of the trees of his forest shall be few, so that a child could write their number.

and the residue of the number of the archers, the mighty men of the children of Kedar, will be few; for Yahweh, the God of Israel, has spoken it."

Lift up your eyes on high, and see who has created these, who brings out their army by number. He calls them all by name. by the greatness of his might, and because he is strong in power, Not one is lacking.
