• Hiligaynon: “Isaias replied, ‘This is the sign that the LORD will-give as a proof that he will-fulfill this promise of his. [You (sing.)] choose from these two: the shadow of the sun will-move-forward/[lit. will-advance] ten intervals in the time-piece or will-move-backward ten intervals.” (Source: Hiligaynon Back Translation)
