G1912–ἐπιβαρέω–epibareō

But if any have caused grief, he hath not grieved me, but in part: that I may not overcharge you all.

ἐπιβαρῶ, epibarō “I may burden”

For ye remember, brethren, our labour and travail: for labouring night and day, because we would not be chargeable unto any of you, we preached unto you the gospel of God.

ἐπιβαρῆσαί epibarēsai “to burden”

Neither did we eat any man's bread for nought; but wrought with labour and travail night and day, that we might not be chargeable to any of you:

ἐπιβαρῆσαί epibarēsai “to be burdensome to”
