New Defender's Study Bible Notes
3:15 To day. The writer makes it clear that the use of “today” in Psalm 95:7 was applicable to any time, not just to David’s time. “Now is the accepted time; behold, now is the day of salvation” (II Corinthians 6:2).
3:15 provocation. “The provocation” refers to the rebellion of the Israelites at the waters of Meribah (Exodus 17:5-7; Numbers 20:7-13), when the Lord provided water out of the rock for them. The word for “provocation” in Psalm 95:8, from which this is quoted, is the Hebrew Meribah.
