'Sure' in the Bible

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

Go, I pray you, make yet more sure, and know and see his place where his haunt is, and who hath seen him there; for it is told me that he dealeth very subtly.

Forgive, I pray thee, the trespass of thy handmaid: for Jehovah will certainly make my lord a sure house, because my lord fighteth the battles of Jehovah; and evil shall not be found in thee all thy days.
