John Gill Commentary Luke 10:23

"And turning to the disciples, he said privately, Blessed [are] the eyes which see the things that ye see:" — Luke 10:23 (ASV)

And he turned him unto his disciples
Both to the twelve apostles, and seventy disciples;

and said privately ;
or to them apart: the phrase "privately" is wanting in the Vulgate Latin version:

blessed are the eyes that see the things that ye see ;
the person of the Messiah, his kingdom setting up in the world, miracles wrought by him, and Satan falling before him; (See Gill on Matthew 13:16).
