'Whether' in the Bible

that by them I may test Israel, whether they will take care to walk in the way of the LORD as their fathers did, or not."

They were for the testing of Israel, to know whether Israel would obey the commandments of the LORD, which he commanded their fathers by Moses.

And they said to him, "Inquire of God, we pray thee, that we may know whether the journey on which we are setting out will succeed."
