G1912–ἐπιβαρέω–epibareō

But if any hath 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 labor and toil: for laboring night and day, because we would not be chargeable to any of you, we preached to you the gospel of God.

ἐπιβαρῆσαί epibarēsai “to burden”

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

ἐπιβαρῆσαί epibarēsai “to be burdensome to”
