8 Diapsalma. The answer of God: “I will give you understanding, and will set you in the way in which you shall go;” I will give you understanding after confession, that you depart not from the way in which you should go; lest you wish to be in your own power. “I will fix Mine Eyes upon you”; so will make sure upon you My Love.
