'Perpetual' in the Bible

Lift up Thy steps to the perpetual desolations, Everything the enemy did wickedly in the sanctuary.

All the days of the afflicted are evil, And gladness of heart is a perpetual banquet.

Wherefore hath this people of Jerusalem Turned back -- a perpetual backsliding? They have kept hold on deceit, They have refused to turn back.

Why hath my pain been perpetual? And my wound incurable? It hath refused to be healed, Thou art surely to me as a failing stream, Waters not stedfast.

After many days thou art appointed, In the latter end of the years thou comest in unto a land brought back from sword, A people gathered out of many peoples, Upon mountains of Israel, That have been for a perpetual waste, And it from the peoples hath been brought out, And dwelt safely have all of them.

and from the time of the turning aside of the perpetual sacrifice, and to the giving out of the desolating abomination, are days a thousand, two hundred, and ninety.
