Deuteronomy 31:19-21

Matthew(i) 19 Now therfore wryte ye this song, & teach it the chyldren of Israell and putt it in theyr mouthes, that this song maye be my witnes vnto the children of Israel. 20 For when I haue brought them into the lande which I sware vnto theyr fathers that runneth with milke and hony, then they wyll eate and fyll them selues and waxe fatt and turne vnto straung Gods and serue theym and rayle on me and breake my testament. 21 And then when much mischyefe and tribulation is come vpon them thys song shall answere before them, and be a wytnes. It shall not be forgotten out of the mouthes of theyr sede: for I know their imagination which they goo aboute euen nowe before I haue brought theym into the lande whych I sware.
