'Guarded' in the Bible

And command the people, saying, Ye are to pass through the border of your brethren the children of Esau, who dwell in Seir; and they will be afraid of you; and ye shall be very guarded:

He found him in a desolate land,in a barren, howling wilderness;He surrounded him, cared for him,and protected him as the pupil of His eye.

the one who told his mother and father, "I don't know them,' and who would neither acknowledge his brothers nor know his own children. For they kept your word and guarded your covenant.
