Deuteronomy 25:17-19

Great(i) 17 Remembre what Amalech dyd vnto the by the waye, whan ye were come out of Egipte, 18 how he met the by the waye, & smote the hyndmost of you, all that were feble & came behynde, when thou wast faynted and werye, and he feared not God. 19 Therfore when the Lorde thy God hath geuen the reast from all thyne enemyes rounde aboute, in the lande whych the Lorde thy God geueth the to enheret and possesse: se that thou put oute the remembraunce of Amalech from vnder heauen and forget not.
