Great(i) 15 & whych was thy gyde in the greate and terrible wyldernesse (wherin were) fyrye serpentes, scorpions, and drouth without any water. But he brought out water for the, euen out of the rocke of flynt: 16 he fedd the in the wildernesse wyth Manna, whych thy fathers knewe not, euen for to humble the, and to proue the, and that he myght so do the good at thy later ende.
