SKY (Heb. shahaq, vapor). A word found only in the plural in the Bible (Ps.18.11; Isa.45.8). The word refers sometimes to the clouds and other times to the firmament. At least once it is used figuratively (Deut.33.26).

In Heb 11:12 we find "the stars of heaven" ("the sky") as a figure of multitude. The conception, however, that the visible "sky" is but the dome-like floor of a higher world often makes it hard to tell whether "heaven" in certain passages may or may not be identified with the sky.
