Hosea 11:10
They shall walk after the LORD: he shall roar like a lion: when he shall roar, then the children shall tremble from the west. They shall walk after the LORD: he shall roar like a lion: when he shall roar, then the children shall tremble from the west.
The verse portrays the Lord calling His people to walk after Him and to follow Him. His roaring like a lion is the sounding of that call to His people. When He roars, His children answer with trembling as they come from the west. The next verse carries the picture forward by showing them returning from Egypt and Assyria like birds and being settled in their homes.
