Deuteronomy 33:9-11

He said to his father and mother, “I have not seen him,” and he did not acknowledge his own brothers or know his own children, for they kept your word, and guarded your covenant. They will teach Jacob your ordinances and Israel your law; they will offer incense as a pleasant odor, and a whole offering on your altar. Bless, O LORD, his goods, and be pleased with his efforts; undercut the legs of any who attack him, and of those who hate him, so that they cannot stand.
