When your fathers - Your ancestors. See this verse explained in the notes on Hebrews 3:9.
Tempted me - Tried me; tried my patience, to see how much I would bear. This does not mean, as it commonly does now with us, to place inducements before one to lead him into sin, but to try one - to put his patience to the test. This they did, in the case referred to, by their obduracy and evil conduct.
Proved me - See the notes at Hebrews 3:9. “And saw my work.” Though they constantly saw my work; saw my gracious interpositions; saw what I was doing for their own good.
