John Gill Commentary Luke 18:29

"And he said unto them, Verily I say unto you, There is no man that hath left house, or wife, or brethren, or parents, or children, for the kingdom of God`s sake," — Luke 18:29 (ASV)

And he said to them
To his disciples, as the Ethiopic version reads; though the Syriac and Persic versions read, "and Jesus said to him"; that is, to Peter; he particularly replied to him:

verily I say to you, there is no man :
not only you shall have peculiar honour done you, as to sit on thrones, and judge the twelve tribes of Israel; but there is not a single person of a more private character,

that has left house ,
or "houses", as read the Syriac and Persic versions;

or parents, or brethren, or wife, or children, for the kingdom of
God's sake :
that is, for Christ's sake, and for the sake of his Gospel, as the other evangelists have it; and which teaches us how to understand the kingdom of God here, and elsewhere.
