'Sure' in the Bible

And I will fasten him as a nail in a sure place; and he shall be for a throne of glory to his father's house.

In that day, saith Jehovah of hosts, shall the nail that was fastened in a sure place give way; and it shall be hewn down, and fall; and the burden that was upon it shall be cut off; for Jehovah hath spoken it.

therefore thus saith the Lord Jehovah, Behold, I lay in Zion for a foundation a stone, a tried stone, a precious corner -'stone of sure foundation: he that believeth shall not be in haste.

He shall dwell on high; his place of defence shall be the munitions of rocks; his bread shall be given him ; his waters shall be sure.

Incline your ear, and come unto me; hear, and your soul shall live: and I will make an everlasting covenant with you, even the sure mercies of David.
