'Blocked' in the Bible

Then many people were gathered, and they blocked off all the springs and the river that flowed through the midst of the land, saying, "Why should the kings of Assyria come and find much water?"

And this same Hezekiah blocked off the flow of the waters of the upper Gihon, and directed them down the west [side] of the city of David. And Hezekiah prospered in all his works.

He has blocked my ways with dressed stones; he has made my paths crooked.
