28The account of the vision is repeated twice in Acts, as Luke has a habit of doing when he wants to emphasize the importance of an event. There are two notable features in the symbolism of the vision. The linen sheet is tied at four corners (four is a symbol of universality, a wind rose); Peter is offered not just “tref” (forbidden) food, but “four-footed animals of the earth, wild beasts, creeping things, and birds of the air,” which, in the prophets, often signified pagan countries (cf. Dan 7–8).
