So why do you all kick at my sacrifice and at my offering that I have commanded in my habitation, and you honor your sons above me making yourselves fat with the best of all the offerings of Israel my people?’ Bible

“you all.” The “you” is plural. Eli and his sons.

“kick” This is idiomatic for “scorn, despise.”

“to make yourselves fat.” This was both figurative and literal, because Eli was fat (1 Sam. 4:18).

“the best.” The Hebrew is literally, “the beginning.” The priests got the first choices and therefore the best parts.
