'Sure' in the Bible

"Therefore, as sure as I live," declares the Lord GOD, "because you've defiled my sanctuary with every loathsome thing and every abomination, I'll restrain myself, and I'll show neither pity nor compassion.

because testing is sure to come. "In putting the sword to the test along with the scepter, it won't keep on rejecting, will it?' declares the Lord GOD."

I'll make sure that you go straight to the Pit, into the lowest part of the earth, where you'll be with people who lived in ancient times. You'll keep company there with the dead, who have gone into the Pit. As a result, your city won't be inhabited. Meanwhile, I will display my glory in the land of the living.

When all of this comes about and you can be sure that it will! they'll learn that a prophet has been in their midst."

This is what the man told me: "Son of Man, watch carefully, listen closely, and remember everything I'm going to be showing you, because you've been brought here to be shown what you're about to see. Be sure that you tell the house of Israel everything that you observe."
