That thou givest them they gather - What thou dost place before them they collect. They have no resources of their own. They can invent nothing; they cannot vary their food by art, as man does; they cannot make use of reason, as man does, or of skill, in preparing it, to suit and pamper the appetite. It comes prepared for them direct from the hand of God.
Thou openest thine hand - As one does who bestows a gift on another. The point in the passage is, that they receive it immediately from God, and that they are wholly dependent on him for it. They have not to labor to prepare it, but it is made ready for them, and they have only to gather it up. The allusion in the "language" may be to the gathering of manna in the wilderness, when it was provided by God, and people had only to collect it for their use. So it is with the brute creation on land and in the waters.
They are filled with good - They are "satiated" with good; that is, They are satisfied with what to them is good, or with what supplies their needs.
That thou givest them they gather - All creatures are formed with such and such digestive organs, and the food proper for them is provided. Infinitely varied as are living creatures in their habits and internal economy, so are the aliments which God has caused the air, the earth, and the waters to produce.
Thou openest thine hand - An allusion to the act of scattering grain among fowls.
That thou givest them they gather,.... What God bestows upon them as a bounty of Providence they take and make use of, and in their way thankfully, and without repining; some gather it up for immediate use and service, and not into barns; others gather it up for time to come, as the ant, Matthew 6:26. Kimchi understands this of a time of scarcity, when they gather here a little and there a little; as he does the following clause of a time of plenty.
Thou openest thine hand, they are filled with good; God, in whose hand all things are, and from whence all things come, opens his hand of providence, and liberally and bountifully gives, as this phrase signifies, Deuteronomy 15:11 and all his creatures are filled with his good things to their satisfaction: and thus the spiritual food which he gives his people, they gather it by the hand of faith, as the Israelites gathered the manna in the wilderness every morning, and according to their eating, what was sufficient for them; and to whom he gives liberally, even all things richly to enjoy; all things pertaining to life and godliness; Christ, and all things along with him; abundance of grace here, and glory hereafter; and they are satisfied with his good things as with marrow and fatness.
