Let them wander up and down for meat, and grudge if they be not satisfied.

King James Translators' Notes

for meat: Heb. to eat

and grudge...: or, if they be not satisfied, then they will stay all night

Jamieson-Fausset-Brown Bible Commentary

15. grudge if, &c.-literally, "they shall stay all night," that is, obtain nothing.

Matthew Henry's Concise Commentary

59:8-17 It is our wisdom and duty, in times of danger and difficulty, to wait upon God; for he is our defence, in whom we shall be safe. It is very comfortable to us, in prayer, to look to God as the God of our mercy, the Author of all good in us, and the Giver of all good to us. The wicked can never be satisfied, which is the greatest misery in a poor condition. A contented man, if he has not what he would have, yet he does not quarrel with Providence, nor fret within himself. It is not poverty, but discontent that makes a man unhappy. David would praise God because he had many times, and all along, found Him his refuge in the day of trouble. He that is all this to us, is certainly worthy of our best affections, praises, and services. The trials of his people will end in joy and praise. When the night of affliction is over, they will sing of the Lord's power and mercy in the morning. Let believers now, in assured faith and hope, praise Him for those mercies, for which they will rejoice and praise him for ever.
