New Defender's Study Bible Notes
112:3 endureth for ever. Psalm 111 stressed the never-ending attributes of God (see note on Psalm 111:8), whereas Psalm 112 follows by noting the never-ending attributes of the redeemed, as centered on their righteousness (Psalm 112:3,6,9), as imputed through faith (Romans 4:5), and created in Christ (Ephesians 2:10).
112:9 endureth for ever. Paul used this verse to encourage generosity among Christian believers (II Corinthians 9:9).
