3. ἄριστον, a meal taken in the morning (compare John 21:4,12,154But when the morning was now come, Jesus stood on the shore: but the disciples knew not that it was Jesus. (John 21:4)
12Jesus saith unto them, Come and dine. And none of the disciples durst ask him, Who art thou? knowing that it was the Lord. (John 21:12)
15So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs. (John 21:15)

, perhaps as late as noon: it is distinguished from “supper” in Luke 14:1212Then said he also to him that bade him, When thou makest a dinner or a supper, call not thy friends, nor thy brethren, neither thy kinsmen, nor thy rich neighbors; lest they also bid thee again, and a recompence be made thee. (Luke 14:12).
