11. That ye may suck. This verse ought to be joined with the preceding verse; for the Prophet explains what shall be the occasion of joy, namely, because the wretched and miserable condition of the Church shall be changed into a happy and prosperous condition. By the word “suck” he makes an allusion to young infants; as if he had said, “That you may enjoy your mother with every advantage, and may hang on her breasts.” Here all believers, whatever may be their age, are compared by him to children, that they may remember their infirmity and may be confirmed by the strength of the Lord; and therefore this metaphor of “sucking” and “milking” ought to be carefully observed.
From the breast of her consolations. Some take the word “consolations” in an active, and others in a passive sense; but I prefer to adopt the passive signification; for he means the consolations which the Church has received, and of which he makes his children partakers. And indeed none can be greater or more abundant, none can be more excellent, than that ground of joy; and this appears more clearly from the following clause, “that ye may be delighted with the brightness of her glory.”
