Albert Barnes Commentary Psalms 77:5

"I have considered the days of old, The years of ancient times." — Psalms 77:5 (ASV)

I have considered the days of old - Rather, “I do consider;” that is, “I think upon.” This refers to his resolution in his perplexity and trouble; the method to which he resorted in examining the subject, and in endeavoring to allay his troubles. He resolved to look at the past. He asked what was the evidence that was furnished on the subject by the former dealings of God with himself and with mankind; what could be learned from those dealings in regard to the great and difficult questions that now so perplexed his mind.

The years of ancient times - The records and remembrances of past ages. What is the testimony that the history of the world bears on this subject? Does it prove that God is worthy of confidence or not? Does it or does it not authorize and justify these painful thoughts that pass through the mind?
