to be or grow fat, or to make fat: to flourish with rich, God-given abundance, or to enrich, satisfy, and honor another with it.
Behind every use of this word stands fat itself, which in the ancient world was the richest and most prized part of an animal and a ready sign of health, wealth, and God's favor. So the word runs from a body growing sleek and well-fed to a whole life made to thrive.
Because fatness meant blessing, the word came to describe God enriching those who are generous, trusting, and hardworking, and even good news putting new life into a person, an image of news that revives the whole body. At a feast it is the host pouring perfumed oil over an honored guest's head, and at the altar it becomes a set phrase for God counting an offering as fat, that is, receiving it gladly.
The same richness can be turned to horror. Isaiah pictures God's sword and the land of Edom soaked and gorged with fat and blood, borrowing the language of blessing to describe slaughter. And Deuteronomy warns that a people who grow fat can forget the God who fed them, so that the gift itself becomes a trap.
