Here's the manner in which The Interlinear Greek-English New Testament (a word-for-word translation of the original writings) records the three (3) passages of
Hebrews 13 wherein the phrase
"them that have the rule over you" appears (see vss. #7, 17 & 24):
"Remember the [ones] leading of you, who have spoke to you the word of God, of whom looking at the result of the conduct imitate their faith."
"Obey ye the [ones] leading of you and submit to [them]; for they watch on behalf of the souls of you as account rendering; in order that with joy this they may do and not groaning; for profitless to you this [would be]."
"Greet ye all the [ones] leading of you and all the saints, greet you the [ones] from Italy."
As noted by Votivesoul, the word OVER does not appear in the original Greek manuscript, and neither does RULE. In each passage it appears the KJV translators have replaced "LEADING" with "rule over," which is NOT an accurate manner of translating the word "leading."
