Zipporah was not slow to interpret the providence.

If Moses had said with himself, So long as I consecrate my child to God by prayer, the seal of the covenant cannot be essential, God taught him his mistake.

As soon as the rite had been performed, we read, "So he let him go." It may be noticed, here, that the unworthy manner in which Zipporah performed the rite, did not make it invalid.
They who fear that their baptism was not solemnized, in all respects, as it should have been, may draw instruction and comfort from this narrative.
There have been instances, within my knowledge, in which one or both of the parents of a child have yielded to some untoward influences, and have withheld the child from being baptized.

While I cannot, and would not, interpret certain events connected with this omission, on the part of some from whom better things might have been expected, nothing has ever impressed me more than the dealings of God with such parents.

I have been made to think by such coincidences, more than once or twice, of Moses in the inn.
