'Lettest' in the Bible

and they will tell it to the inhabitants of this land, who have heard that thou, Jehovah, art in the midst of this people, that thou, Jehovah, lettest thyself be seen eye to eye, and that thy cloud standeth over them, and that thou goest before them, in a pillar of cloud by day, and in a pillar of fire by night;

That thou turnest thy spirit against God, and lettest words go out of thy mouth?

Thou lettest thy mouth loose to evil, and thy tongue frameth deceit;
