Deuteronomy 33:9

33:9 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.

Malachi 2:4-6

2:4 Then you will know that I sent this commandment to you so that my covenant may continue to be with Levi,” says the Lord who rules over all. 2:5 “My covenant with him was designed to bring life and peace. I gave its statutes to him to fill him with awe, and he indeed revered me and stood in awe before me. 2:6 He taught what was true; sinful words were not found on his lips. He walked with me in peace and integrity, and he turned many people away from sin.
