“Behold, he smote the rock, that the waters gushed out, and the streams overflowed; can he give bread also? can he provide flesh for his people?”
King James Version (KJV)
78:18 Tempted - Desired a proof of God's power. Lust - Not for their necessary subsistence, but out of an inordinate and luxurious appetite.
78:22 Trusted not - That he both could, and would save them from the famine which they feared.
