'Stretched out' in the Bible

Then the LORD said unto Joshua, "Stretch out the spear that is in thine hand toward Ai, for I have given thee it." And Joshua stretched out the spear that was in his hand, toward the city.

And the lyers-await rose quickly out of their places, and ran, as soon as Joshua had stretched out his hand, and they entered into the city, and took it, and hasted and set it on fire.

For Joshua plucked not his hand back again which he stretched out with the spear, until they had utterly destroyed all the inhabiters of Ai.
