He said

"John said"

I am a voice, crying in the wilderness

John is saying that Isaiah's prophecy is about himself. The word "voice" here refers to the person who is crying out in the wilderness. AT: "I am the one calling out in the wilderness" (See: rc://en/ta/man/translate/figs-metonymy)

Make the way of the Lord straight

Here the word "way" is used as a metaphor. AT: "Prepare yourselves for the Lord's arrival the same way that people prepare the road for an important person to use" (See: rc://en/ta/man/translate/figs-metaphor)
