'Set A Guard' in the Bible

Am I [the] sea, or a sea monster, that you set a guard over me?

Set a guard, O Lord, over my mouth;Keep watch over the door of my lips [to keep me from speaking thoughtlessly].

set a guard upon yourselves, that ye be not stupified by surfeiting and drunkenness, or by the disquietudes of this life, and so that day come upon you with a surprize.
