Psalms 81:10

Psa 81:10 I [am] the LORD thy God, which brought thee out of the land of Egypt: open thy mouth wide, and I will fill it.

Ver. 10. Open thou thy mouth wide, &c. ] If thou be straitened, it is not in me, but in thine own bowels; he secretly taxeth them for their ολιγοπιστια and their ολιγοφυχια in prayer, their faithlessness and faint-heartedness, whereby they do deny, as it were, their own prayers: ask largely, and speed accordingly.
