Charles Spurgeon Commentary Matthew 14:30-32

"But when he saw the wind, he was afraid; and beginning to sink, he cried out, saying, Lord, save me. And immediately Jesus stretched forth his hand, and took hold of him, and saith unto him, O thou of little faith, wherefore didst thou doubt? And when they were gone up into the boat, the wind ceased." — Matthew 14:30-32 (ASV)

But when he saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me. And immediately Jesus stretched forth his hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt? And when they were come into the ship, the wind ceased.

The Greek word implies that the wind was tired, weary, "done up," as we say. It had had its boisterous time, and spent its force; and now it knew its Lord's voice, and, like a tired child, fell asleep.
