'Fatness' in the Bible

My soul [my life, my very self] is satisfied as with marrow and fatness,And my mouth offers praises [to You] with joyful lips.

You crown the year with Your bounty,And Your paths overflow.

Their eye bulges from fatness [they have more than the heart desires];The imaginations of their mind run riot [with foolishness].

My knees are unsteady from fasting;And my flesh is gaunt and without fatness.
