Thus my heart was grieved, and I was pricked in my reins.
Ver. 21. Thus my heart was grieved] Heb. leavened and soured, sc. with the greatness of godly sorrow, et quasi aceto acri perfundebatur, it was steeped, as it were, in vinegar. So Peter wept bitterly; waters of Marah flowed from his eyes.
And I was pricked in my reins] Pricked at heart, as those, Acts 2:37, put to as much pain as those that have the stone in the kidneys, exceedingly grieved for my misconstruing and miscensuring of God's ways and people.
