The descendants of Abraham found themselves enslaved down in Egypt building the treasure cities of Pharaoh. Because they were in covenant with God, however, it was as if God himself was enslaved, too. In fact, part of Psalm 81 gives us a portrait of God walking through Egypt, as if he were right there on the scene where his people were being mistreated. God says, in effect, “I was there, and I saw you with a burden on your back. I saw you with a basket of bricks in your hands. I heard you struggling with the language of the Egyptians.” And as Israel’s covenant partner, God obligated himself to act on their behalf. That’s why his message to the obstinate Pharaoh was, “Let my people go!”
God’s message to his own people was, “Open your mouth wide, and I will fill it” (Psalm 81:10). That’s an illustration from the hedgerows—a picture of baby birds being fed by mother bird in the nest. A baby bird is nothing but a big open beak with a straggly bit of flesh attached to it. It’s the picture of absolute dependence and expectancy. God was reminding his people to trust him; to depend on him—to rely on him, even when life was difficult. Or, in the words of Jesus: “Apart from me, you can do nothing” (John 15:5). This spiritual dynamic is still true today. God is the ultimate covenant partner on whom we can always depend. We just need to learn how to open our mouths wide.
