Phebe is still vary feeble & low. ... I felt the power of the destroyer resting upon me in the fore part of the day.
In the evening Phebe for the first time during her sickness began to lay hold on faith for her recovery. Her faith was strong in God. We laid hold on faith together repented of all our sins & confessed them befor God & covenanted to keep his Commandments. I had some oil that was Consecrated for my anointing while in kirtland. I again Consecrated it before God for anointing the sick. I bowed myself down before the Lord & prayed with my companion & anointed her [with] oil in the name of the Lord. I laid my hands upon her in the name of JESUS CHRIST and rebuked the fever the destroyier the deadly malidy that was praying upon her system & thank God we both obtained a great blessing in so doing & according to her faith her fever left her & praised be the name of GOD for we will ever keep his commandments & trust in him. Praise the Lord O my soul for all of his wonderful acts.
