'Feast' in the Bible

So Abner came to David to Hebron, and twenty men with him. And David made Abner and the men that were with him a feast.

Now after two full years, Absalom had men cutting the wool of his sheep in Baal-hazor, which is near Ephraim: and he sent for all the king's sons to come to his feast.

But Absalom went on requesting him till he let Amnon and all the king's sons go with him. And Absalom made a great feast like a feast for a king.

Then two hundred men from Jerusalem who were invited [as guests to his sacrificial feast] went with Absalom. They went innocently and knew nothing [about his plan against David].
