What does Matthew 19:10 mean?
The disciples have listened to Jesus' response to the Pharisees' question about the grounds for divorce. The Pharisees have asked for Jesus' perspective about what "indecency" means in Deuteronomy 24:1, where the law seems to allow a man to divorce his wife for this reason. Jesus has stated that divorce is never allowed except in cases of sexual immorality (Matthew 19:1–9).The disciples respond to Jesus' declaration by saying that it's better not to get married at all. Most commentators agree that what the disciples mean by this is that, if divorce is not an option, it would be better not to marry than to be stuck for life in an unhappy marriage. The presumed right to divorce if things did not go well was held dearly by many Jewish men of the time, including many of the religious leaders. Divorce had become common in Israel. The disciples said, perhaps foolishly, that marriage is too big of a risk without the possibility of divorce.
Jesus will respond that though some can live without marriage, not everyone can.
