Acts 2:18 - Matthew Poole's English Annotations on the Holy Bible

On my servants and on my handmaidens; to show what all ought to be, that hope to receive any benefit or comfort from the promises of God, either in the law or gospel, the Old or New Testament; viz. such as seek and serve God; but to the disobedient and unbelieving there is not a comfortable word in all the book of God. Some read without the pronoun, on servants and handmaids; to show that God doth not despise men of the lowest rank and condition in the world, but that the promise of the Spirit is made unto them also.
