Habakkuk 1:9 - Matthew Poole's English Annotations on the Holy Bible

They, Chaldeans, and in particular these fierce and swift horsemen, shall come all, with one purpose, on the same design, to enrich themselves by making a prey of all. Their faces shall sup up as the east wind: either thus, their very countenances shall be as blasting, pestiferous, and dangerous as is the east wind in those countries; or thus, all they can sup up, or lay hold on, they will carry eastward; or thus, when you are devoured, they shall set their faces eastward to devour others in those coasts. They shall gather the captivity; prisoners or captives, called here the captivity, to express the extremity thereof. As the sand, both for easiness of gathering, and the multitudes of captives gathered.
