A number of trinitarians couple John 8:58 with John 18: 1-6 where the officers and soldiers fell down when Jesus identified himself by saying ego eimi.
Noted trinitarian scholar A.T. Robertson asks what caused these hundreds of officers and soldiers to fall. One suggestion was "supernatural power exerted by Jesus" (which seems most likely). He continues by admitting that one of the very oldest complete manuscripts (300's A.D.), Uncial Manuscript B, "adds Iesous which must mean simply: 'I am Jesus.'" - Word Pictures in the New Testament, p. 284, vol. v.
In addition, the very trinitarian United Bible Societies notes for the use of ego eimi at John 18:5:
"In considering the variant readings of this verse it must be recalled that normally scribes contracted the name 'Iesous' [Jesus] to IC. On the one hand, it is possible that, if ho Iesous ['the Jesus' or OIC in contracted form] stood originally after AUTOIC [as found in manuscript B], the words may have been accidentally omitted through an oversight in transcription (AUTOICOIC)"
This is the reason that the UBS assigned an accuracy rating (how likely the term they chose as the one to use in their text is to be the original term) of "C."
This means, according to their rating system, that using ego eimi as what was originally written by the inspired writer has "considerable degree of doubt." - p. 251, A Textual Commentary on the Greek New Testament, UBS, 1971.
Dr. William Barclay, noted trinitarian NT scholar and translator, also tells us about this incident:
"The officers, therefore, were the Jewish police force. But there was a band of Roman soldiers there too." He continues by telling us that even if we take the smallest number of Roman soldiers indicated by the NT Greek words used, it would still amount to two hundred men. - p. 222, The Gospel of John, vol. 2, The Daily Study Bible Series, Westminster Press, 1975.
Barclay explains the event: "(ii) It shows us his [Jesus'] authority. There he was, one single, lonely, unarmed figure; there they were, hundreds of them, armed and equipped. Yet face to face with him, they retreated and fell to the ground. There flowed from Jesus an authority which in all his loneliness made him stronger than the might of his enemies. (iii) It shows us that Jesus chose to die. Here again it is clear that he could have escaped death if he so wished." - p. 223.
There is this to be recognized from Barclay's information:
Two hundred (at least) Roman soldiers were there who probably didn't understand Jesus' language. And even if they did understand, they surely wouldn't understand that a mistranslation of a Jewish OT word (ehyeh, Heb. or ho own, Sept.) meant that Jesus was claiming to be God (nor would they even care if he really did claim to be that Jewish God).
And yet, these, 200 Roman soldiers were tumbled over along with the others. It could not be because they recognized ego eimi as meaning Jesus was really the true God of the universe! These were Roman soldiers!
It must be, as suggested, that Jesus (or the Father in heaven) applied an actual force to knock them down to show that Jesus could escape them if he so wished.
It should be noted that the following trinitarian-translated Bibles translate this as Jesus saying, “I am he”: KJV; ASV; NIV; NASB; RSV; NRSV; and the majority of others. This would not have happened if those noted trinitarian translators and scholars had believed ego eimi here was being used as a name for God.
