'Sure' in the Bible

And I will raise me up a faithful priest, that shall do according to that which is in mine heart and in my mind: and I will build him a sure house; and he shall walk before mine anointed for ever.

If he say thus, It is well; thy servant shall have peace: but if he be very wroth, then be sure that evil is determined by him.

I pray thee, forgive the trespass of thine handmaid: for the LORD will certainly make my lord a sure house; because my lord fighteth the battles of the LORD, and evil hath not been found in thee all thy days.
