'Whether' in the Bible

that by them I may prove Israel, whether they will keep the way of Yahweh to walk therein, as their fathers did keep it, or not."

They were [left], to prove Israel by them, to know whether they would listen to the commandments of Yahweh, which he commanded their fathers by Moses.

They said to him, "Please ask counsel of God, that we may know whether our way which we go shall be prosperous."
