Psalms 50:9

I will take no bullock out of thy house
That is, will accept of none; such sacrifices being no more agreeable to the will of God, ( Hebrews 10:5 Hebrews 10:6 Hebrews 10:8 ) ; the "bullock" is mentioned, that being a principal creature used in sacrifice; as also the following,

[nor] he goats out of thy folds;
the reasons follow.
