'Perpetual' in the Bible

O thou enemy, destructions are come to a perpetual end: and thou hast destroyed cities; their memorial is perished with them.

Lift up thy feet unto the perpetual desolations; even all that the enemy hath done wickedly in the sanctuary.

And he smote his enemies in the hinder parts: he put them to a perpetual reproach.

For I have said, “Goodness and lovingkindness will be built up forever;In the heavens [unchangeable and majestic] You will establish Your faithfulness.”
