This verse was quoted in Matthew 3: 1-3, ” In those days John the Baptist came, preaching in the Desert of Judea and saying, ‘Repent, for the Kingdom of Heaven is near.’ This is he who was spoken of through the prophet Isaiah…” John the Baptist proclaimed a very specific message…”Look at your actions and behavior…is your life where it needs to be with the Lord?” A more modern-day expression of this would be – “You need to get your life back on the straight and narrow.”
