given to (greedy of) filthy lucre

Concise Bible Dictionary:

“Gain,” such as a judge should not have wished for or accepted (1 Sam. 8:3). In the New Testament it is called “filthy” or “base gain”; the desire for it rendered a man ineligible for the position of elder in the church (1 Tim. 3:3,8; Titus 1:7,11; 1 Pet. 5:2).
