왕이 모든 여자보다 에스더를 더욱 사랑하므로 저가 모든 처녀보다 왕의 앞에 더욱 은총을 얻은지라 왕이 그 머리에 면류관을 씌우고 와스디를 대신하여 왕후를 삼은 후에
Shulchan Arukh, Even HaEzer
There is a commandment to delight a groom and bride and dance before them and tell them they are beautiful and kind. Even if they aren't pretty. Rem"a: We see rabbi Yehuda the son of allay was dancing before the bride and nullifying the words of the torah to enter the bride to the canopy.
Kitzur Shulchan Arukh
It is a mitzvah to rejoice the groom and bride, and to dance before her and say that she is beautiful and gracious, (from the expression, "She found grace and favour before him");4Esther 2:17. and we find that Rabbi Yehuda Bar Illai used to dance before the bride.5Maseches Kesubos 17a.
