Verse 17. - Evening, and morning (comp. Genesis 1:5, 8, etc.), and at noon, will I pray, and cry aloud. From this passage and from Daniel's conduct (Daniel 6:10) we learn that devout Israelites habitually offered prayer to God at these three times of the day. The "morning "and "evening" devotions were doubtless suggested by the law of the morning and evening sacrifice (Exodus 29:38-42); but the midday prayer, being nowhere commanded, can only be ascribed to natural piety. And he shall hear my voice. Constant unremitting prayer is certain of an answer. Compare the parable of the importunate friend (Luke 11:5-8).

55:16-23 In every trial let us call upon the Lord, and he will save us. He shall hear us, and not blame us for coming too often; the oftener the more welcome. David had thought all were against him; but now he sees there were many with him, more than he supposed; and the glory of this he gives to God, for it is he that raises us up friends, and makes them faithful to us. There are more true Christians, and believers have more real friends, than in their gloomy hours they suppose. His enemies should be reckoned with, and brought down; they could not ease themselves of their fears, as David could, by faith in God. Mortal men, though ever so high and strong, will easily be crushed by an eternal God. Those who are not reclaimed by the rod of affliction, will certainly be brought down to the pit of destruction. The burden of afflictions is very heavy, especially when attended with the temptations of Satan; there is also the burden of sin and corruption. The only relief under it is, to look to Christ, who bore it. Whatever it is that thou desirest God should give thee, leave it to him to give it in his own way and time. Care is a burden, it makes the heart stoop. We must commit our ways and works to the Lord; let him do as seemeth him good, and let us be satisfied. To cast our burden upon God, is to rest upon his providence and promise. And if we do so, he will carry us in the arms of his power, as a nurse carries a child; and will strengthen our spirits by his Spirit, so that they shall sustain the trial. He will never suffer the righteous to be moved; to be so shaken by any troubles, as to quit their duty to God, or their comfort in him. He will not suffer them to be utterly cast down. He, who bore the burden of our sorrows, desires us to leave to him to bear the burden of our cares, that, as he knows what is best for us, he may provide it accordingly. Why do not we trust Christ to govern the world which he redeemed?Evening, and morning, and at noon, will I pray,.... These being the stated times of prayer with the Jews, and which continued to later ages, Daniel 6:10. These times, they say (b), were fixed by Abraham, Isaac, and Jacob: the morning prayer by Abraham, according to Genesis 22:3, the prayer of the "minchah" by Isaac, according to Genesis 24:63; and the evening prayer by Jacob, according to Genesis 28:11. The prayer of the evening was at the time of the evening sacrifice, to which it is compared, Psalm 141:2. This was at the ninth hour, at which time Peter and John went up to the temple to pray; and Cornelius prayed in his own house, Acts 3:1. The prayer of the morning was at the time of the morning daily sacrifice, and was about the third hour of the day; at which time the apostles met together for prayer on the day of Pentecost, Acts 2:1; and that at noon was at the sixth hour of the day; at which time Peter went up to the housetop to pray, Acts 10:9. And now, though we are not tied down to these exact and precise times of prayer, yet this teaches us that we ought to pray frequently and constantly, and that a day should not pass without it; and the morning and evening seem to be very proper seasons for it, seeing the mercies of the Lord are new every morning; and we should be thankful for them and the mercies of the night past, and implore divine protection and grace for the day following; and at evening we should express our thankfulness for the mercies of the day, and commit ourselves and families into the hands of God, who is Israel's Keeper, that neither slumbers nor sleeps;

and cry aloud; denoting the distress he was in, the fervency of his prayer, and the importunity of it;

and he shall hear my voice; this he might be assured of, from the general character of God, as a God hearing prayer, and from his own special and particular experience of the truth of it, and from the promises made unto him.
