The balcony window on the south side portrays the major prophets of the Old Testament and the prophet who served as a link between the Old Testament and the New, John the Baptist.
In the left lancet Isaiah stands in the presence of the Lord. He is overwhelmed by his sense of worthlessness and sin and cries out, “Woe is me! For I am lost: for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips ..." Then flew one of the Serafim to me, having in his hand a burning coal which he had taken with tongs from the altar. And he touched my mouth and said, behold, this has touched your lips; your guilt is taken away, and your sin forgiven. Then said I, "Here I am! Send me.” (Isaiah 6: 5-9)
Underneath the ﬁgure of Isaiah, the Prophet Daniel is portrayed. Daniel was thrown into the lions’ den because he prayed to the God of Israel. But God sent His angel and shut the lion's mouth, and they have not hurt me because I was found blameless before Him. (Daniel 6: 22)
The right lancet shows the Prophet Jeremiah and in the background the ruins of Jerusalem, destroyed by the king of Babylon. How lonely sits the city that was full of people! How like a widow is she become, she that was great among the nations. (Lamentations 1: 1) But Jeremiah also brings a great word of hope: For I know the plans that I have for you, says the Lord, plans for welfare and not for evil, to give you a future and a hope. Then you will call upon Me and come and pray to Me, I will hear you. (Jeremiah 29: 11-12)
The top section of this lancet portrays the calling of the Prophet Ezekiel: And when I looked, behold, a hand was stretched out to me, and lo, a written scroll was in it; and he spread it before me... and he said to me, "Mortal, eat this scroll and go and speak to the house of Israel.” (Ezekiel 3: 1)
The large figure in the two lower sections depicts the prophet who was the forerunner of Jesus. He is clad in a garment of camel's hair, holding a lamb in his arms, which recalls his prophecy: Behold, the Lamb of God, Who takes away the sin of the world. (John 1: 29)
