dead
sn Chapter 2 starts off with a participle, although you were dead, that is left dangling. The syntax in Greek for vv. 1-3 constitutes one incomplete sentence, though it seems to have been done intentionally. The dangling participle leaves the readers in suspense while they wait for the solution (in v. 4) to their spiritual dilemma.

Eph 2: 2

(KJV)

the spirit
sn The ruler of the kingdom of the air is also the ruler of the spirit that is now energizing the sons of disobedience. Although several translations regard the ruler to be the same as the spirit, this is unlikely since the cases in Greek are different (ruler is accusative and spirit is genitive). To get around this, some have suggested that the genitive for spirit is a genitive of apposition. However, the semantics of the genitive of apposition are against such an interpretation (cf. ExSyn 100).

tn Grk “working in.”
the sons of disobedience,
sn Sons of disobedience is a Semitic idiom that means “people characterized by disobedience.” However, it also contains a subtle allusion to vv. 4-10: Some of those sons of disobedience have become sons of God.

Eph 2: 3

Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.

among whom
sn Among whom. The relative pronoun phrase that begins v. 3 is identical, except for gender, to the one that begins v. 2 (ἐν αἵς [en hais], ἐν οἵς [en hois]). By the structure, the author is building an argument for our hopeless condition: We lived in sin and we lived among sinful people. Our doom looked to be sealed as well in v. 2: Both the external environment (kingdom of the air) and our internal motivation and attitude (the spirit that is now energizing) were under the devil’s thumb (cf. 2 Cor 4:4).

sn Eph 2:1-3. The translation of vv. 1-3 is very literal, even to the point of retaining the awkward syntax of the original. See note on the word dead in 2:1.
