A.T. Robertson Commentary Mark 14:56

"For many bare false witness against him, and their witness agreed not together." — Mark 14:56 (ASV)

Their witness agreed not together (ισα α μαρτυρια ουκ ησαν). Literally, the testimonies were not equal. They did not correspond with each other on essential points.

Many were bearing false witness (εψευδομαρτυρουν, imperfect, repeated action)

against him . No two witnesses bore joint testimony to justify a capital sentence according to the law (Deuteronomy 19:15). Note imperfects in these verses (55-57) to indicate repeated failures.
