Deliver our lives from death - She had learned, either from the spies or otherwise, that all the inhabitants of the land were doomed to destruction, and therefore she obliges them to enter into a covenant with her for the preservation of herself and her household.

And that ye will save alive my father, and my mother, and my brethren, and my sisters,.... She makes no mention of any husband or children she had, as harlots seldom have, and which seems to confirm her character as such; and so Abarbinel observes, that her father's house is only mentioned to tell us that she had no husband, for she was an harlot and had no children, and puts her father and mother in the room of an husband, and her brethren and sisters in the room of children:

and all that they have; not their substance only, but their children more especially, the children of her brethren and sisters:

and deliver our lives from death; here she manifestly includes herself, and requests the saving of her life, and the lives of all her relations, when she knew the inhabitants of the city would be all put to death upon the taking of it: thus she provided for the safety of her family, as Noah in another case and manner did, Hebrews 11:7; and indeed seemed more concerned for them than for herself; and thus souls sensible of their own estate and condition, by nature and grace, are very solicitous for the salvation of their relations and friends, Romans 9:3.

And that ye will save alive my father, and my mother, and my brethren, and my sisters, and all that they have, and deliver our lives from death.

2:13 All that they have - That is, their children, as appears from Jos 6:23.

2:8-21 Rahab had heard of the miracles the Lord wrought for Israel. She believed that his promises would certainly be fulfilled, and his threatenings take effect; and that there was no way of escape but by submitting to him, and joining with his people. The conduct of Rahab proved that she had the real principle of Divine faith. Observe the promises the spies made to her. The goodness of God is often expressed by his kindness and truth, Ps 117:2; in both these we must be followers of him. Those who will be conscientious in keeping promises, are cautious in making them. The spies make needful conditions. The scarlet cord, like the blood upon the doorpost at the passover, recalls to remembrance the sinner's security under the atoning blood of Christ; and that we are to flee thereto for refuge from the wrath of a justly offended God. The same cord Rahab used for the saving of these Israelites, was to be used for her own safety. What we serve and honour God with, we may expect he will bless, and make useful to us.
