'Fatted' in the Bible

Adonijah sacrificed sheep, oxen, and fatted cattle by the Serpent Stone near En-rogel, inviting all of his relatives, the king's sons, and all of the men of Judah who worked for the king,

And he has sacrificed oxen and fatted cattle and sheep in abundance, and has invited all the sons of the king and Abiathar the priest and Joab the captain of the host; but Solomon thy servant has he not invited.

For he is gone down this day, and has sacrificed oxen and fatted cattle and sheep in abundance, and has invited all the king's sons, and the captains of the host, and Abiathar the priest; and behold, they eat and drink before him, and say, God save king Adonijah!

Ten fat oxen, and twenty oxen out of the pastures, and an hundred sheep, beside harts, and roebucks, and fallowdeer, and fatted fowl.
