John Trapp on Psalms 78:15

Verſ. 15. Hee clave the rocks] And ſet them abroach, both that in Rephidim, Exod. 17. and the other in Cadeſh, Num. 20. Moſes Nehamides, on Exod. 17. ſaith, that the old Jew-doctors held that the Rock of Rephidim not only yeelded waters like a river all thoſe forty years wherein they were in the wilderneſs, but followed them alſo there whitherſoever they went. This agreeth well with that of the Apoſtle St. Paul. 1 Cor. 10.4. who ſweetly allegorizeth this hiſtory.

As out of the great deeps] i. e. In great abundance. Rocks ſooner yeeld fire than water; but what cannot God do?Ad [illegible: 1 word] uſque.
