Song of Songs 4:2

Your teeth are like a counted flock, etc. This praise, too, is expressed in terms of a woman’s beauty.

Your teeth. Are fine and white and arranged in their proper order like wool and like the order of a flock of ewes, selected from the rest of the flock by count and number, and are assigned to a clever and capable shepherd to be careful with their wool, because they make them into fine woolen garments. They watch them from the time of birth, that the wool should not become soiled, and they wash them daily.

All of which are perfect. An expression of perfection, [as in,] “There is no perfection מְתם in my flesh,” i.e., “whole” תְּמִימוֹת=מַתְאִימוֹת, entires in O.F.

And [none are] blemished. There is no miscarriage or defect among them. This allegory was stated in reference to: The mighty men of Yisroel, who cut down and consume their enemies surrounding them with their teeth, and yet they distance themselves from robbing from [Bnei] Yisroel and from lewdness, so that they should not become sullied with sin. This praise was stated concerning the twelve thousand men who mobilized against Midyan with a count and a number, of whom not one was suspected of lewdness, as it is stated, “and not a man among us is missing.” And even for improper thoughts they brought atonement offerings. Also, they were not suspected of theft, for Scripture attests regarding them, “And they took all the spoils... and they brought it to Moshe and to Elazar the kohein, etc.,” and not one of them concealed even one cow or one donkey.
