So I gave them up unto their own hearts’ lust - Margin, as in Hebrew, to the hardness of their own hearts. Literally, “I sent them, or I dismissed them, to the hardness of their hearts.” I suffered them to have what, in the hardness of their hearts they desired, or what their hard and rebellious hearts prompted them to desire: I indulged them in their wishes. I gave them what they asked, and left them to themselves to work out the problem about success and happiness in their own way - to let them see what must be the result of forsaking the true God. The world - and the church too - has been often suffered to make this experiment.
And they walked in their own counsels - As they thought wise and best. Compare Acts 7:42; Acts 14:16; Romans 1:24; Psalms 78:26-37.
