New Defender's Study Bible Notes
22:28 ancient landmark. See also Proverbs 23:10; Deuteronomy 19:14; 27:17. The lands were originally divided by the Lord (Genesis 10:32), when He “set the bounds of the people” (Deuteronomy 32:8). The “earth is the LORD’s” (Psalm 24:1), and He can give and transfer the lands according to His will (Acts 17:26). These God-given boundaries should be respected.
22:28 thy fathers. There is also an important spiritual application in this verse. The “landmark” may be a spiritual standard, established by our spiritual forefathers, God-honoring and God-blessed. There is always a tendency for each new generation to try to modernize the ways of their fathers and, in view of the universal law of decay, this is more often a mistake.
