'Stretched' in the Bible

But the dove did not find a resting place for the sole of her foot, and she returned to him into the ark, for the waters [were still] on the face of the earth. And he stretched out his hand and took her, and brought her to himself into the ark.

And Abraham stretched out his hand and took the knife to slaughter his son.

And Israel stretched out his right hand and put [it] on the head of Ephraim (now he was the younger), and his left hand on the head of Manasseh, crossing his hands, for Manasseh [was] the firstborn.
