Albert Barnes Commentary Deuteronomy 29:11

"your little ones, your wives, and thy sojourner that is in the midst of thy camps, from the hewer of thy wood unto the drawer of thy water;" — Deuteronomy 29:11 (ASV)

The covenant was national, and therefore embraced all the elements which make up the nation. The “little ones” would of course be represented by their parents or guardians; the absent (Deuteronomy 29:15) by those present; nor were the servants and proselytes to be excluded . The text is justifiably cited in justification of the Church’s practice of admitting “little ones” into covenant with God by Baptism, and accepting promises made on their behalf by sponsors.
