'Sure' in the Bible

And I took unto me to witness, sure witnesses, Urijah the priest, and Zechariah the son of Jeberechiah.

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 is fastened in a sure place be removed, and be cut down, and fall; and the burden that was upon it shall be cut off: for Jehovah hath spoken.

Therefore thus saith the Lord Jehovah: Behold, I lay for foundation in Zion a stone, a tried stone, a precious corner-stone, a sure foundation: he that trusteth shall not make haste.

And my people shall dwell in a peaceable habitation, and in sure dwellings, and in quiet resting-places.

he shall dwell on high, the fortresses of the rocks shall be his high retreat; bread shall be given him, his water 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, the sure mercies of David.
