So the king commanded all his people, “Every time a boy is born to the Hebrews, you must throw him into the Nile River, but let all the girl babies live.”
Then Moses and the Israelites sang this song to the Lord: “I will sing to the Lord, because he is worthy of great honor. He has thrown the horse and its rider into the sea.
The Lord said to Moses, “Tell Aaron: ‘Take the walking stick in your hand and stretch your hand over the rivers, canals, ponds, and pools in Egypt.’ The water will become blood everywhere in Egypt, both in wooden buckets and in stone jars.”
Then the Lord said to Moses, “Tell Aaron to hold his walking stick in his hand over the rivers, canals, and ponds. Make frogs come up out of the water onto the land of Egypt.”
So you must show mercy to others, or God will not show mercy to you when he judges you. But the person who shows mercy can stand without fear at the judgment.
