Revelation of Jesus Christ
From the KJV 1611 with Strong's Concordance
G3801
ὁ ὢν καὶ ὁ ἦν καὶ ὁ ἐρχόμενος
ho on kai ho en kai ho erchomenos
{ho own kahee ho ane kahee ho er-khom'-en-os}
A phrase combining G3588 with the present particle and imperfect ofG1510 and the present particle of G2064 by means of G2532; the one being and the one that was and the one coming, that is, the Eternal, as a divine epithet of Christ. (Each 'and' (G2532) was ommited from the phrase because of limited space.).
The following translates multiple Greek words:
be
Revelation 16:5.
come
Revelation 1:4, 8; 4:8; 11:17.
