Charles H. Spurgeon on Psalms 95:9

Your fathers tempted me. There are two ways of interpreting the words which follow. As tempting God is nothing else than yielding to a diseased and unwarrantable craving after proof of his power, we may consider the verse as connected throughout, and read, They tempted me and proved me, although they had already seen my work. God very justly complains, that they should insist upon new proof, after his power had been already amply testified by undeniable evidences. There is another meaning, however, that may be given to the term "proved", —according to which, the meaning of the passage would run as follows: —Your fathers tempted me in asking where God was, notwithstanding all the benefits I had done them; and they proved me, that is, they had actual experience of what I am, inasmuch as I did not cease to give them open proofs of my presence, and consequently they saw my work. —John Calvin.
