Ulangan 33:9

33:9 He said to his father and mother, “I have not seen him,” ¹ 

and he did not acknowledge his own brothers

or know his own children,

for they kept your word,

and guarded your covenant.

[33:9]  ¹ sn This statement no doubt alludes to the Levites’ destruction of their own fellow tribesmen following the golden calf incident (Exod 32:25-29).
