Why did Jesus use a Greek proverb when He spoke Aramaic to Saul in Acts 26:14?

Saul spoke Greek, Aramaic, Hebrew, and Latin (there are many references). Jesus spoke Aramaic, Greek, and Hebrew (again there are many references). In Acts 26:14, Paul (who at this time was using his second name Paul, being a Roman, rather than his first name Saul), testified to Agrippa, possibly in Greek, that when Jesus confronted him on the road to Damascus, Jesus spoke to him in Aramaic and said, "It is hard for thee to kick against the pricks" (KJV), or "it is hard for thee to kick against the goad" (in other versions), which is a Greek proverb. Is there any significance or relevance here of Jesus speaking in Aramaic and using a Greek proverb to Saul (who became Paul later on), who spoke four languages?
