Albert Barnes Commentary Proverbs 22:28

"Remove not the ancient landmark, Which thy fathers have set." — Proverbs 22:28 (ASV)

A protest against the grasping covetousness (Isaiah 5:8) which is regardless of the rights of the poor, upon whose inheritance people encroach (compare the margin reference). The common reference of these words to the “landmarks” of thought or custom, however natural and legitimate, is foreign to the writer's original meaning.
