'Dug' in the Bible

Then I went to the Euphrates, and dug, and took the belt from the place where I had hidden it; and behold, the belt was marred, it was profitable for nothing.

Shall evil be recompensed for good? for they have dug a pit for my soul. Remember how I stood before you to speak good for them, to turn away your wrath from them.

Let a cry be heard from their houses, when you shall bring a troop suddenly on them; for they have dug a pit to take me, and hid snares for my feet.
