New Defender's Study Bible Notes
23:5 cup runneth over. Ancient wells in Israel have been found with “cups” for the sheep, into which the shepherd would scoop up water from the well.
23:6 house of the LORD. The “house of the LORD” means the household of God—that is, God’s family. Compare Ephesians 5:19-22.
23:6 for ever. The sheep is safe with the good shepherd both in time and in eternity. The six verses of the psalm, capped with the magnificent assurance of Psalm 23:6, correlate with the six uses of “shepherd” in John 10 and the six references in other books of the New Testament to Christ as our shepherd.
