Charles Spurgeon Commentary Luke 15:25-27

"Now his elder son was in the field: and as he came and drew nigh to the house, he heard music and dancing. And he called to him one of the servants, and inquired what these things might be. And he said unto him, Thy brother is come; and thy father hath killed the fatted calf, because he hath received him safe and sound." — Luke 15:25-27 (ASV)

And as he came and drew near to the house, he heard music and dancing. And he called one of the servants, and asked what these things meant. And he said to him, Your brother has come; and your father has killed the fatted calf, because he has received him safe and sound. And he was angry,

He did not want the fatted calf killed. If this reprobate brother were allowed to come in at the back door and eat with the servants, he thought that was quite good enough; but for this rebel to be treated as his equal—he could not bear that!
