Deuteronomy 19:5
as when a man goes into the forest with his neighbor to chop wood, and his hand fetches a stroke with the axe to cut down the tree, and the head slips from the handle, and lights on his neighbor, so that he dies; he shall flee to one of these cities and live:
Numbers 35:25
and the congregation shall deliver the manslayer out of the hand of the avenger of blood, and the congregation shall restore him to his city of refuge, where he was fled: and he shall dwell therein until the death of the high priest, who was anointed with the holy oil.
2 Kings 6:5-7
But as one was felling a beam, the axe head fell into the water. Then he cried, and said, "Alas, my master! For it was borrowed."
Proverbs 27:12
A prudent man sees danger and takes refuge; but the simple pass on, and suffer for it.
Isaiah 32:2
A man shall be as a hiding place from the wind, and a covert from the storm, as streams of water in a dry place, as the shade of a large rock in a weary land.
