'Sure' in the Bible

And I will raise up for myself a faithful priest, who shall do according to what is in my heart and in my mind; and I will build him a sure house; and he shall walk before mine anointed continually.

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

Go, I pray you, make yet more sure, and know and see his place where his track is, who has seen him there; for it is told me that he deals very subtilly.

And see, and ascertain all the lurking-places where he hides himself, and come ye again to me with sure information, that I may go with you; and it shall come to pass, if he be in the land, that I will search him out throughout the thousands of Judah.
