'Concerning' in the Bible

When God saw their deeds, that they turned from their wicked way, then God relented concerning the calamity which He had declared He would bring upon them. And He did not do it.

He prayed to the Lord and said, “Please Lord, was not this what I said while I was still in my own country? Therefore in order to forestall this I fled to Tarshish, for I knew that You are a gracious and compassionate God, slow to anger and abundant in lovingkindness, and one who relents concerning calamity.
