Psalms 78:22

Lastly, when both these things have been briefly touched, afterwards he is evidently following out the order of the narrative. "Because they believed not in God, nor hoped in His saving health." For when he had told why fire was lighted in Jacob, and anger went up upon Israel, that is to say, "because they believed not in God, nor hoped in His saving health:" immediately subjoining the evident blessings for which they were ungrateful, he saith, "and He commanded the clouds above, and opened the doors of Heaven." "And He rained upon them manna to eat, and gave them bread of Heaven." "Bread of angels man did eat: dainties He sent them in abundance." "He brought over the South Wind from Heaven, and in His virtue He led in the South West Wind." "And He rained upon them fleshes like dust, and winged fowls like the sand of the sea." "And they fell in the midst of their camp, around their tabernacles." "And they ate and were filled exceedingly; and their desire He brought to them: they were not deprived of their desire." Behold why He had delayed. But what He had delayed let us hear. "Yet the morsel was in their mouths, and the anger of God came down upon them." Behold what He had delayed. For before "He delayed:" and afterwards, "fire was lighted in Jacob and anger went up upon Israel." He had delayed therefore in order that He might first do what they had believed that He could not do, and then might bring upon them what they deserved to suffer. For if they placed their hope in God, not only would their desires of the flesh but also those of the spirit have been fulfilled. […]

Because they believed not in God,.... That he was able to give them bread, and provide flesh for them, or bring them through the wilderness to Canaan's land, as he had promised.

Those cannot be said to trust in God's salvation as their felicity at last who cannot find in their hearts to trust in his providence for food convenient in the way to it. That which aggravated their unbelief was the experience they had had of the power and goodness of God,

Because they believed not in God, and trusted not in his salvation. This is the master sin, the crying sin. Like Jeroboam, the son of Nebat, it sins and makes Israel to sin; it is in itself evil and the parent of evils. It was this sin which shut Israel out of Canaan, and it shuts myriads out of heaven. God is ready to save, combining power with willingness, but rebellious man will not trust his Saviour, and therefore is condemned already. In the text it appears as if all Israel's other sins were as nothing compared with this; this is the peculiar spot which the Lord points at, the special provocation which angered him. From this let every unbeliever learn to tremble more at his unbelief than at anything else. If he be no fornicator, or thief, or liar, let him reflect that it is quite enough to condemn him that he trusts not in God's salvation.
