'Fasten' in the Bible

And when Peter saw it, he answered unto the people, Ye men of Israel, why marvel ye at this man? or why fasten ye your eyes on us, as though by our own power or godliness we had made him to walk?

The angel said to him, "Fasten your belt and put on your sandals." Peter did so. Then the angel said to him, "Put on your cloak and follow me."

but Paul having gathered together a quantity of sticks, and having laid them upon the fire, a viper -- out of the heat having come -- did fasten on his hand.
