Charles Ellicott Commentary Proverbs 1:28

"Then will they call upon me, but I will not answer; They will seek me diligently, but they shall not find me:" — Proverbs 1:28 (ASV)

Then shall they call upon me.— They did not call upon Him in an acceptable time, in a day of salvation (Isaiah 49:8), while He was near (Isaiah 55:6); so at last the master of the house has risen up, and shut-to the door (Luke 13:25), and will not listen to their cries.

They shall seek me early.— As God had done, daily rising up early, and sending the prophets to them (Jeremiah 7:25).
