'Fierceness' in the Bible

and say to them, 'Ye do not bring in the captives hither, for, to guilt against Jehovah on us, ye are saying to add unto our sin and unto our guilt? for abundant is the guilt we have, and the fierceness of anger on Israel.'

Now -- with my heart -- to make a covenant before Jehovah, God of Israel, and the fierceness of His anger doth turn back from us.

Now be ye not stiffnecked, as your fathers were, but yield yourselves unto the LORD, and enter into his sanctuary, which he hath sanctified for ever: and serve the LORD your God, that the fierceness of his wrath may turn away from you.
