'Stretched out' in the Bible

The dove could not find a resting place for its feet because water still covered the surface of the entire earth, and so it returned to Noah in the ark. He stretched out his hand, took the dove, and brought it back into the ark.

Israel stretched out his right hand and placed it on Ephraim's head, although he was the younger. Crossing his hands, he put his left hand on Manasseh's head, for Manasseh was the firstborn.
