Swallow

Heb. deror, i.e., “the bird of freedom” (Ps. 84:3; Prov. 26:2), properly rendered swallow, distinguished for its swiftness of flight, its love of freedom, and the impossibility of retaining it in captivity. In Isa. 38:14 and Jer. 8:7 the word thus rendered (‘augr) properly means “crane” (as in the R.V.).
