And also upon the servants and upon the handmaids in those days will I pour my Spirit. Men servants and maidservants should partake of the gifts and grace of the Spirit in great, abundance; and many of them were effectually called by grace, through the ministry of the word; and some servants became ministers of it; all which appears from Co1 7:21; for that is not true what the Jews (p) say, the Shechinah or divine Majesty does not rest but upon a wise man, and one mighty and rich; or prophecy, as Maimonides (q) has it. (p) T. Bab. Sabbat, fol. 92. 1. (q) Moreh Nevochim, par. 2. c. 32.
