How do you say father forgive them for they do not know what they do in Hebrew?

Answer 1

אבא, תסלח להם מפני שהם לא יודעים משהם עושים

Aba, tislach lahem mipnei shehem lo yod'im mah shehem osim

Note: Jesus would most likely have said this in Aramaic, not Hebrew, as Aramaic was the lingua franca in Judea at the time.

Answer 2

Father, forgive them = av, slach lahem (אב, סלח להם)

Answer 3

From Luke 23:34אָבִי סְלַח לָהֶם כִּי אֵינָם יׂדְעִים מָה הֵם עׂשִׂים

avi, slach lahem ki einam yod'im mah hem osim

Answer 4

אָבִי סְלַח לָהֶם כִּי אֵינָם יוֹדְעִים מָה הֵם עוֹשִׂיםavi slach lahem ki einam yod'im ma hem osim.
