Adam Clarke on Song of Solomon 2:8

Behold, he cometh leaping - This appears to be highly characteristic of the gambols of the shepherds, and points out the ecstasy with which those who were enamoured ran to their mates. It is supposed that the second day's eclogue begins at this verse. The author of what was then called A New Translation of Solomon's Song, observes,

1. The bride relates how the bridegroom, attended by his companions, had come under her window, and called upon her to come forth and enjoy the beauties of the spring, Sol 2:9-11, etc.

2. She then returns to her narration, Sol 3:1. The bridegroom did not come according to her wishes. Night came on; she did not find him in her bed; she went out to seek him; found him, and brought him to her mother's pavilion, Sol 3:4; and then, as before, conjures the virgins not to disturb his repose, Sol 3:5.
