Charles Ellicott Commentary Joshua 2:13

"and that ye will save alive my father, and my mother, and my brethren, and my sisters, and all that they have, and will deliver our lives from death." — Joshua 2:13 (ASV)

Save alive my father, and my mother, and my brethren, and my sisters. —Whatever Rahab may have been herself, her acknowledgment of all her family is observable. She was in no way separated or degraded from their society. When we remember what Moses describes the Canaanites to have been (in certain passages of the Pentateuch, as Leviticus 18:24-28; Leviticus 20:22–23), and compare this chapter, we may reasonably conclude Rahab to have been morally not inferior to her countrymen at that time, but rather their superior.

We are reminded that the publicans and harlots were not the worst members of the evil and adulterous generation to whom the Word of God came. They believed John the Baptist, and were among the most constant hearers of the true Joshua (Matthew 21:32; Luke 15:1).
