John Gill Commentary Leviticus 6:29

"Every male among the priests shall eat thereof: it is most holy." — Leviticus 6:29 (ASV)

And all the males among the priests shall eat thereof ,
&c.] As of the meat offerings, (Leviticus 6:18) and this shows that not the single priest that offered only ate of it, (Leviticus 6:26) but his male children, and not those only, but those of other priests then upon duty, or in the court:

it [is] most holy; (See Gill on Leviticus 6:25).
