See thy way in the valley - The valley of Hinnom, where they offered their own children to Moloch, an idol of the Ammonites.
A swift dromedary traversing her ways - Dr. Blayney translates, “A fleet dromedary that hath taken to company with her.” Dr. Dahler rather paraphrases, thus: -
Semblable a une dromedaire en chaleur,
Qui court d’une tote a l’autre.
“Like to a dromedary in her desire for the male,
Which runs hither and thither.”
This is an energetic comparison; and shows the unbridled attachment of those bad people to idolatry, and the abominable practices by which it was usually accompanied.
