Job 12:20

He removeth away the speech of the trusty, and taketh away the understanding of the aged.

He removeth away the speech of the trusty - the approved, those of approved eloquence-`those secure in their eloquence:' ex. gr., the speakers in the gate (Isaiah 3:3). (Beza.)

Understanding - literally, 'taste' - i:e., insight or spiritual discernment, which experience gives the aged. The same Hebrew word х Ta`am (H2940)] is applied to Daniel's wisdom in interpretation (Daniel 2:14)
