Good and upright is the LORD: therefore will he teach sinners in the way.
Good - benignant (cf. "thy goodness," Psalms 25:7).
Upright is the Lord. Based on Deuteronomy 32:4. "Upright" implies that God's character accords with the most perfect role of right (unlike the pagan idea of deity); "therefore" He cannot but be faithful to His promises (Psalms 25:5-6); and teach His people the right way of salvation (Psalms 32:8). But it is such "sinners" ( chaTaa'iym (H2400)) as do not persevere in sin, but flee to the grace of God for pardon; not hardened transgressors ( pesha`iym (H6588)), nor those persisting in daring impiety (resha`iym).
