'Slippeth' in the Bible

As when a man goeth into the wood with his neighbour to hew wood, and his hand fetcheth a stroke with the axe to cut down the tree, and the head slippeth from the helve, and lighteth upon his neighbour, that he die; he shall flee unto one of those cities, and live:

For I said, Hear me, lest otherwise they should rejoice over me: when my foot slippeth, they magnify themselves against me.

When I said, My foot slippeth; thy mercy, O LORD, held me up.
