per-pet’-u-al, per-pet’-u-al-i, pur-pe-tu’-i-ti (`olam, netsach, [~tamidh):

"Perpetually" is the rendering of `adh, properly "progress," "duration," hence, long or indefinite time, eternity (usually in the King James Version rendered "for ever " ), in Am 1:11, "His anger did tear perpetually"; and of kol ha-yamim, "all the days" (1Ki 9:3; 2Ch 7:16, "my heart shall be there perpetually"; compare Mt 28:20, pasas tas hemeras, literally, "all the days").

Perpetuity occurs in the Revised Version (British and American) of Le 25:23,30, "The land shall not be sold in perpetuity," "The house .... shall be made sure in perpetuity."

Perpetual is frequent in the Apocrypha, most often as the translation of aionios and kindred words, e.g. Judith 13:20, "a perpetual praise"; The Wisdom of Solomon 10:14, "perpetual glory," the Revised Version (British and American) "eternal"; Ecclesiasticus 11:33, "a perpetual blot," the Revised Version (British and American) "blame for ever"; 1 Macc 6:44, "a perpetual name," the Revised Version (British and American) "everlasting"; aenaos, "ever-flowing," occurs in The Wisdom of Solomon 11:6 (so the Revised Version); endeleches, "constant" (Ecclesiasticus 41:6, "perpetual reproach").

For "perpetual" (Jer 50:5; Hab 3:6) the Revised Version has "everlasting"; for "the old hatred" (Eze 25:15), "perpetual enmity"; for "perpetual desolation" (Jer 25:12) "desolate forever," margin "Hebrew `everlasting desolations.’"
