Isaiah 48:1-2

The Lord called on His people to pay attention to what He had to say to them and to respond appropriately (cf. Isaiah 42:18; Isaiah 46:12). The many descriptions of the Israelites in these verses reminded them of their origins and their identity, their commitments to and their appreciation for Yahweh, and their present relationship with Him. In view of all this, they needed to heed what He said. They had not done that as they should have in the past.
