In mine house; in my temple, to serve me there as priests, which eunuchs were not allowed to do, Leviticus 21:17, &c.; Deuteronomy 23:1. Within my walls; in the courts of my temple, which were encompassed with walls. This seems to be added with respect to the people, who were admitted into the court, but not into the house itself. A place and a name better than of sons and of daughters; a far greater blessing and honour than that of having posterity, which was but a temporal mercy, and that common to the worst of men; even my favour, and my Spirit, and eternal felicity.
