Mark 14:31

But he spake the more vehemently
With a louder voice; with more spirit and eagerness; in a more peremptory and self-confident way. If I should die with thee, I will not deny thee in any wise.
The Syriac version adds, "O my Lord", my dear Lord, I will never deny thee upon any consideration whatever; and the Persic version, O Lord: likewise also said they all;
as he said, so said "all the disciples", as the Syriac version reads it; (See Gill on Matthew 26:35).
