Exodus 23:25.
25:”You shall serve the Lord your God, and he will bless your bread and your water, and I will take sickness away from among you.”
God of heavenly powers, by the might of your command you drive away from our bodies all sickness and all infirmity: Be present in your goodness with your servant, that his weakness may be banished and his strength restored; and that, his health being renewed, he may bless your holy Name; through Jesus Christ our Lord, Amen.
