Harden not your heart, by wilful disobedience and obstinate unbelief, rebelling against the light, and resisting the Holy Ghost, and his clear discoveries of the truth of the gospel. As in the provocation; as you did in that bold and wicked contest with God in the wilderness. Or, as in Meribah, which was the proper name of the place where that happened, and which also was called Massah, as is evident from Exodus 17:7 Deuteronomy 33:8. As in the day of temptation; in the day in which you tempted me. Or, as in the day of Massah, i.e. when you were at Massah.
