(20) Thy good spirit.--Probably a reference to Numbers 11:17; Numbers 11:25. The epithet given to the Spirit is in Psalm 143:10. But His teaching function occurs here only, and is a remarkable anticipation of the New Testament.

Verse 20. - Thou gavest them also thy good Spirit to instruct them. The "good Spirit" of God is mentioned in Psalm 143:10; and the fact of God's "instructing and teaching" men in Psalm 32:8. But instruction by God's Spirit is nowhere else distinctly mentioned in the Old Testament.

9:4-38 The summary of their prayers we have here upon record. Much more, no doubt, was said. Whatever ability we have to do any thing in the way of duty, we are to serve and glorify God according to the utmost of it. When confessing our sins, it is good to notice the mercies of God, that we may be the more humbled and ashamed. The dealings of the Lord showed his goodness and long-suffering, and the hardness of their hearts. The testimony of the prophets was the testimony of the Spirit in the prophets, and it was the Spirit of Christ in them. They spake as they were moved by the Holy Ghost, and what they said is to be received accordingly. The result was, wonder at the Lord's mercies, and the feeling that sin had brought them to their present state, from which nothing but unmerited love could rescue them. And is not their conduct a specimen of human nature? Let us study the history of our land, and our own history. Let us recollect our advantages from childhood, and ask what were our first returns? Let us frequently do so, that we may be kept humble, thankful, and watchful. Let all remember that pride and obstinacy are sins which ruin the soul. But it is often as hard to persuade the broken-hearted to hope, as formerly it was to bring them to fear. Is this thy case? Behold this sweet promise, A God ready to pardon! Instead of keeping away from God under a sense of unworthiness, let us come boldly to the throne of grace, that we may obtain mercy, and find grace to help in time of need. He is a God ready to pardon.Thou gavest also thy good spirit to instruct them,.... In the knowledge of the laws delivered to them; the spirit of prophecy, according to Ben Melech, and which Aben Ezra interprets of the spirit put upon the seventy elders, Numbers 11:17,

and withheldest not thy manna from their mouth; all the while they were in the wilderness, until they came to Canaan's land; called the Lord's manna, because prepared by him, and given by him to them; a part or portion and gift from the Lord, as Ben Melech, from whence it had its name, see Exodus 16:15

and gavest them water for their thirst; which seems to have respect to the last rock stricken for them, after their many provocations in the wilderness, Numbers 20:11.
