G1912–ἐπιβαρέω–epibareō

Now if any one has caused sorrow, it has been caused not so much to me, as in some degree--for I have no wish to exaggerate--to all of you.

ἐπιβαρῶ, epibarō “I may burden”

For you remember, brethren, our labour and toil: how, working night and day so as not to become a burden to any one of you, we came and proclaimed among you God's Good News.

ἐπιβαρῆσαί epibarēsai “to burden”

nor did we eat any one's bread without paying for it, but we laboured and toiled, working hard night and day in order not to be a burden to any of you.

ἐπιβαρῆσαί epibarēsai “to be burdensome to”
