Psalms 106:35

But were mingled among the heathen - Among the nations; by intermarriage, and by commerce. They suffered them to remain in the land, contrary to the command of God, and thus greatly exposed and endangered the purity of their religion and their own morals. See Judges 2:2; Judges 3:5.

And learned their works - Their practices; their customs and habits: learned to live as they did. This was an illustration of the danger of contact with the wicked and the worldly. What occurred in their case has often occurred since in the history of the people of God, that by “mingling” with the world they have learned to practice their “works;” have become conformed to their manner of living, and have thus lost their spirituality, and brought dishonor on the cause of religion. There is some proper sense in which the people of God are not to be conformed to the world; in which, though living among them, they are to be separate from them; in which, though they are parts of the same nation, and live under the same government and laws, they are to be a distinct and special people, ruled supremely by higher laws, and having higher and nobler ends of life. Rom 12:2; 2 Corinthians 6:14.
