The swift is a small migratory bird often confused with the swallow. Although they are similar, the two birds come from different families. Swifts are strong fliers that can travel short distances at over 100 m. p. h. They spend much of their time feeding on airborne insects.
The prophet Jeremiah must have known the migrating habits of the swift. He spoke of this bird and others that “observe the time of their coming.” Unlike these birds, he observed, the rebellious people of the nation of Judah “do not know the judgment of the Lord” (Jer. 8:7).
