As a piece of a pomegranate - See on Song 4:3 (note).

As a piece of a pomegranate are thy temples within thy locks. The same descriptions are given in Song 4:3; See Gill on Song 4:3; and these are repeated, to show the reality of the church's beauty, and for the sake of confirmation; and that it still continued the same, notwithstanding her failings and infirmities; and that Christ had the same esteem of her, and love to her, he ever had. That part of the description, respecting the church's lips and speech, in Song 4:3; is here omitted, though added at the end of Song 6:6; by the Septuagint; but is not in the Hebrew copies, nor taken notice of in the Targum; yea, the Masorah, on Song 4:2, remarks some words as only used in that place, and therefore could not be repeated here in the copies then in use.
