'Exert' in the Bible

Fear of me should not terrify you;the pressure I exert against you will be light.

If the ax is dull, and one does not sharpen its edge,then one must exert more strength;however, the advantage of wisdom is that it brings success.

All of you, gather together and listen! Who among them announced these things? The Lord's ally will carry out his desire against Babylon; he will exert his power against the Babylonians.
