Whilst their children remember their altars and their groves by the green trees upon the high hills.
Whilst their offspring held in mind the altars of idolatry and the groves for false worship set beneath green trees on the hills, the verse points to Judah's children remembering the places where the people had turned aside to heathen rites. That remembrance was not fleeting but showed a worship of idols that had taken deep root in the life of the nation. What the parents had established at those hilltop shrines was thus carried forward from one generation to the next.
