A dramatic depiction of Genesis 18, Old Testament, God appearing to Abraham and Sarah. From King James translation: 

18 And the Lord appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;

² And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,

³ And said, My Lord, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant:

⁴ Let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree:

⁵ And I will fetch a morsel of bread, and comfort ye your hearts; after that ye shall pass on: for therefore are ye come to your servant. And they said, So do, as thou hast said.

⁶ And Abraham hastened into the tent unto Sarah, and said, Make ready quickly three measures of fine meal, knead it, and make cakes upon the hearth.

⁷ And Abraham ran unto the herd, and fetcht a calf tender and good, and gave it unto a young man; and he hasted to dress it.

⁸ And he took butter, and milk, and the calf which he had dressed, and set it before them; and he stood by them under the tree, and they did eat.

⁹ And they said unto him, Where is Sarah thy wife? And he said, Behold, in the tent.

¹⁰ And he said, I will certainly return unto thee according to the time of life; and, lo, Sarah thy wife shall have a son. And Sarah heard it in the tent door, which was behind him.

 The top part of the panel has been cut centuries ago, likely during the Protestant Reformation, since it was a depiction of God. A foot is still visible coming down from the sky, surrounded by illuminated clouds.
