Charles Spurgeon Commentary Hebrews 11:31

"By faith Rahab the harlot perished not with them that were disobedient, having received the spies with peace." — Hebrews 11:31 (ASV)

By faith the harlot Rahab perished not with them that believed not, when she had received the spies with peace.

Here you have faith uniting itself with the people of God: she perished not with them that believed not, for she had come out from among them and allied herself with the people of God by receiving the spies.
