This is clear from the meaning of 'lying with' as being joined to; and from the meaning of 'a beast' as a good affection with people who are good, and an evil affection with those who are evil, dealt with in 45, 46, 142, 143, 246, 714, 715, 719, 776, 2781, 3518, 3519, 5198, 7424, 7523, 7872, 9090, thus evil desires, at this point the desires of self-love. The term 'evil desires' is used to mean evil affections.

Among the Prophets therefore, and consistently throughout the Old Testament Word, like matters are represented by various kinds of living creatures. There are two kinds of beasts - evil ones, because they are harmful, and good ones, because they are gentle. Evil [and harmful] things in man were meant by such beasts as bears, wolves, and dogs, while good and gentle things were meant by beasts such as calves, sheep, and lambs. As the subject here is those persons who are to be regenerated, 'the beasts' are good and gentle ones, which mean affections. Things of a baser nature that derive from the body are called 'wild animals of the earth'. These are desires and pleasures.
