We have a little sister,
Our anonymous commentator believes this is the bride now unselfishly wanting to reach out to another who is not espoused to Christ and the “being spoken for” implies God’s timing in her salvation.
Gill and Moody Stuart both believe the little sister is the Gentile church, so called by the Jewish church; for as the church catholic, or universal, with respect to its parts, is called a mother, as often in this Song; so these parts, with respect to each other, as the Jewish and Gentile churches, may be called sisters; and the rather, as they belong to the same Father and family, are partakers of the same grace, and are of the same faith. The Gentile church is not only sister to the Jewish church, but to Christ, and therefore she says, not I, but we, have such a sister; of which relation, see Song of Solomon 4:9; also that she stood in this relation to Christ and to the Jewish church before the coming of Christ, and before the Gospel was preached to her, and she was called and separated from the world; as elect Gentiles are also called the sheep of Christ, and children of God, before that time, John 10:16. This church is described as a “little sister,” younger in age than the Jewish church; the same with the younger son and brother, in the parable of the prodigal; little in esteem among men, especially the Jews, Ephesians 2:11; As a further description of her, it is added,
and she hath no breasts:
is not arrived to years of ripeness, nor marriageable; see Ezekiel 16:7; the time of her open espousal to Christ was not yet come: at this time she had no ministers nor ordinances, from whence she could have the sincere milk of the word, or share it with others; and it was some time after the Gospel came among the Gentiles before they had a settled ministry;
what shall we do for our sister in the day when she shall be spoken for?
“what shall be done for her?” being moved with pity to her, in her forlorn and helpless condition, like a little infant, Ezekiel 16:4; and willing to do anything for her that lay in her power, though seeming at a loss to know what to do for her: the believing Jews were very (helpful) to the Gentiles, in carrying the Gospel among them at first; and in supplying them with ministers, and with money too, to carry on the interest of Christ among them. The Jewish church here is not forgetful of the chief and principal agent, Christ, and therefore says, what shall we do? She was willing to do what she could; but she knew all would be insignificant without Christ, his agency and blessing. The time has come when she should be wooed or treated with for marriage, by the ministers of the word, at the first preaching of the Gospel to her; and this question exercised the early church (Acts 15); after receiving the Gospel of Christ, submitting to his ordinances, and professing his name, Acts 28:22. Now the old church might be concerned, that she might stand firm to her faith and the profession of it, notwithstanding the reproaches and persecutions of men.
