How oft did they provoke him in the wilderness,.... Where they were not only at his mercy, having nothing to help themselves with, but had many singular mercies bestowed upon them; and yet were continually committing such sins against God as provoked the eyes of his glory; ten times they tempted him, the Lord says, Num 14:22, therefore that dispensation is called the provocation and day of temptation; for it was a series of rebellion and sin, Psa 95:8, and grieve him in the desert; which signifies the same as before, and is spoken after the manner of men, Gen 6:6 and like a tender parent grieved at the disobedience of his child, and that he is obliged to take the rod and chastise it. The prophet Isaiah says, they "vexed" or "grieved his Holy Spirit", Isa 63:10, the same word is there used as here; compare with it Eph 4:30.
