God also gave them up. He abandoned them, or he ceased to restrain them, and suffered them to act out their sentiments, and to manifest them in their life. This does not imply that he exerted any positive influence in inducing them to sin, any more than it would if we should seek, by argument and entreaty, to restrain a headstrong youth, and when neither would prevail, should leave him to act out his propensities, and to go as he chose to ruin. It is implied in this,

(1.) that the tendency of man was to these sins;

(2) that the tendency of idolatry was to promote them; and

(3) that all that was needful, in order that men should commit them, was for God to leave him to follow the devices and desires of his own heart. Comp. Ps 81:12; 2 Th 2:10,12.

To dishonour. To disgrace, Ro 1:26,27.

Between themselves. Among themselves; or mutually. They did it by unlawful and impure connexions with one another.
