Air

Vine's Expository Dictionary of NT Words

1: ἀήρ

(Strong's #109 — noun, masculine — aer — ah-ayr' )

Eng., "air," signifies "the atmosphere," certainly in five of the seven occurrences, Acts 22:23; 1 Corinthians 9:26; 14:9; Revelation 9:2; 16:17 , and almost certainly in the other two, Ephesians 2:2; 1 Thessalonians 4:17 .

2: οὐρανός

(Strong's #3772 — — ouranos — oo-ran-os' )

denotes "the heaven." The RV always renders it "heaven." The AV translates it "air" in Matthew 8:20 . In the phrase "the fowls (or birds) of the heaven" the AV always has "air;" "sky" in Matthew 16:2,3; Luke 12:56; in all other instances "heaven." The word is probably derived from a root meaning to cover or encompass. See HEAVEN , SKY.
