'Digging' in the Bible

Also in thy skirts hath been found the blood of innocent needy souls, Not by digging have I found them, but upon all these.

As the digging of a well, is for its waters, So she hath digged for her wickedness, Violence and spoil is heard in her, Before My face continually are sickness and smiting.

Should good be paid back with evil? Yet they are virtually digging a pit to kill me. Just remember how I stood before you pleading on their behalf to keep you from venting your anger on them.
