In Isaiah 38:14 Jeremiah 8:7 , two birds are mentioned, the sus and the AGUR , the first rendered in our version crane, the second swallow. Bochart says the sus, or sis, is the swallow; the agur, the crane. The numidian crane, supposed to be referred to, is about three feet in length, is bluish-grey, with the cheeks, throat, breast, and tips of the long hinder feathers black, with a tuft of white feathers behind each eye. "Like a crane, or a swallow, so did I chatter:" there is peculiar force and beauty in the comparison here made between the dying believer and migratory birds about to take their departure to a distinct but more genial clime. They linger in the scenes which they have frequented, but instinct compels them to remove.
