'Falsifying' in the Bible

saying, When will the new moon be gone, that we may sell corn? and the sabbath, that we may set forth wheat? making the ephah small and the shekel great, and falsifying the balances for deceit:

But we have rejected the hidden things of shame, not walking in deceit, nor falsifying the word of God, but by manifestation of the truth commending ourselves to every conscience of men before God.
