(19) If ye be willing and obedient, ye shall eat the good of the land.--The promise of temporal blessings as the reward of a true repentance, instead of the spiritual peace and joy of Psalm 51:8-12, fills us at first with a sense of disappointment. It has to be remembered, however, that the prophet spoke to those who were unjust and selfish, and who were as yet far from the broken and contrite heart of the true penitent. He was content to wake up in them the dormant sense of righteousness, and to lead them to recognise the moral government of God. In the long run they would not be losers by a change of conduct. The choice of eating or "being eaten" (the "devoured" of Isaiah 1:20), enjoying a blameless prosperity, or falling by the sword, was placed before those to whom the higher aspirations of the soul were little known. Such is, at all times, one at least of the methods of God's education of mankind.

Verse 19. - If ye be willing and obedient. Rosenmüller explains this as equivalent to "if ye be willing to obey" (cf. Ezekiel 3:7); but perhaps it is better to give each verb its separate force: "If you consent in your wills, and are also obedient in your actions" (so Kay). Ye shall eat the good of the land; i.e. there shall be no invasion; strangers shall not devour your crops (see ver. 7); you shall consume them yourselves. "The good of the land" is a common expression for its produce (Genesis 45:18, 20; Ezra 9:12; Nehemiah 9:36; Jeremiah 2:7).

1:16-20 Not only feel sorrow for the sin committed, but break off the practice. We must be doing, not stand idle. We must be doing the good the Lord our God requires. It is plain that the sacrifices of the law could not atone, even for outward national crimes. But, blessed be God, there is a Fountain opened, in which sinners of every age and rank may be cleansed. Though our sins have been as scarlet and crimson, a deep dye, a double dye, first in the wool of original corruption, and afterwards in the many threads of actual transgression; though we have often dipped into sin, by many backslidings; yet pardoning mercy will take out the stain, Ps 51:7. They should have all the happiness and comfort they could desire. Life and death, good and evil, are set before us. O Lord, incline all of us to live to thy glory.If ye be willing and obedient,.... The Targum adds, "to my Word": the Word made flesh, and dwelling among them; who would have gathered the inhabitants of Jerusalem to his ministry, to attend his word and ordinances, but their rulers would not:

ye shall eat the good of the land; the land of Canaan; as the Jews held the possession of that land, before the times of Christ, by their obedience to the laws of God, which were given them as a body politic, and which, so long as they observed, they were continued in the quiet and full enjoyment of all the blessings of it; so, when Christ came, had they received, embraced, and acknowledged him as the Messiah, and been obedient to his will, though only externally, they would have remained in their own land, and enjoyed all the good things in it undisturbed by enemies.
