Psalms 145:15

The eyes of all wait upon thee - What a fine figure! The young of all animals look up to their parents for food. God is here represented as the universal Father, providing food for every living creature.

In due season - The kind of food that is suited to every animal, and to all the stages of life in each animal. This is a wonderful mystery. It is a fact that all are thus provided for; but how is it done? All expect it from God, and not one is dsappointed! For,

The eyes of all wait upon thee - Margin, Look unto thee. All creatures, on the land, in the air, in the waters; all in heaven; all throughout the universe. That is, It is as if all directed their eyes to thee imploringly for the supply of their needs. To no one else can they look for those things which are needful for them. A universe thus looks every day, every hour, every moment, to its God! How sublime the scene!

And thou givest them their meat in due season - See the notes at Psalm 104:27, where the same words occur.

145:15 All - Of all living creatures. Wait - Expect their supplies wholly from thy bounty. Expectation is here figuratively ascribed to brute creatures.
