ukjv@Joshua:23:13 @ Know for a certainty that the LORD your God will no more drive out any of these nations from before you; but they shall be snares and traps unto you, and scourges in your sides, and thorns in your eyes, until all of you perish from off this good land which the LORD your God has given you.

ukjv@1Samuel:23:23 @ See therefore, and take knowledge of all the lurking places where he hides himself, and come all of you again to me with the certainty, and I will go with you: and it shall come to pass, if he be in the land, that I will search him out throughout all the thousands of Judah.
