'Sure' in the Bible

In that day,” declares the Lord of hosts, “the peg (Eliakim) that was driven into the firm place will give way; it will even break off and fall, and the burden hanging on it will be cut off, for the Lord has spoken.”

Therefore the Lord God says this,“Listen carefully, I am laying in Zion a Stone, a tested Stone,A precious Cornerstone for the [secure] foundation, firmly placed.He who believes [who trusts in, relies on, and adheres to that Stone] will not be disturbed or give way [in sudden panic].

He will dwell on the heights,His place of defense will be the fortress of rocks,His bread will be given him;His water will be permanent.

“Incline your ear [to listen] and come to Me;Hear, so that your soul may live;And I will make an everlasting covenant with you,According to the faithful mercies [promised and] shown to David.
