'Fat' in the Bible

Then he said to them, “Go, eat of the fat, drink of the sweet, and send portions to him who has nothing prepared; for this day is holy to our Lord. Do not be grieved, for the joy of the Lord is your strength.”

“They captured fortified cities and a fertile land.They took possession of houses full of every good thing,Hewn cisterns, vineyards, olive groves,Fruit trees in abundance.So they ate, were filled and grew fat,And reveled in Your great goodness.
