4 For in fact when we were with you, we were telling you in advance that we would suffer affliction, and so it has happened, as you well know.

Darby

4 for also, when we were with you, we told you be^D8791forehand we are about to be in tribulation, even as also it came to pass, and ye know.)

Darby Bible Notes

be - Or 'we are to be,' that is, such is the lot of Christians; but 'told you beforehand' seems to make it applicable to the Thessalonians. I suspect both were in the apostle's mind; but it is added to ver. 3, and not the repetition of it.

KJV

4 For verily, when we were with you, we told you before that we should suffer tribulation; even as it came to pass, and ye know.

Strong's

4 For ^G1063 verily^G2532, when^G3753 we were^G2258 with^G4314 you^G5209, we told^G4302 you^G5213 before^G4302 that^G3754 we should^G3195 suffer tribulation^G2346; even^G2532 as^G2531 it came to pass^G1096, and^G2532 ye know^G1492.
