Footnotes:
Proverbs 18:9 This verse so reads in The Septuagint (Greek translation of the Old Testament). Its statement squarely addresses the problem of whether one has a moral right to neglect his body by “letting nature take its unhindered course” in illness.
In
1 Timothy 5:23 the Apostle Paul encouraged Timothy, "drink no longer water, but use a little wine for thy stomach's sake and thine often infirmities"
There is a passage in the book of Ecclesiasticus (also known as "The Wisdom of Jesus the Son of Sirach" or just "Sirach") that speaks of medication and treatment by a doctor. This book is found in the 1611 King James Version and some newer than 1611 King James Version Bibles but was later deleted. It is also found among the Dead Sea Scrolls and in several other Bible versions.
Ecclesiasticus 38:1-15 reads:
1 Honour physicians for their services,
for the Lord created them;
2 for their gift of healing comes from the Most High,
and they are rewarded by the king.
3 The skill of physicians makes them distinguished,
and in the presence of the great they are admired.
4 The Lord created medicines out of the earth,
and the sensible will not despise them.
5 Was not water made sweet with a tree
in order that its power might be known?
6 And he gave skill to human beings
that the pharmacist might be glorified in his marvellous works.
7 By them the physician heals and takes away pain;
8 the pharmacist makes a mixture from them.
God’s works will never be finished;
and from him health spreads over all the earth.
9 My child, when you are ill, do not delay,
but pray to the Lord, and he will heal you.
10 Give up your faults and direct your hands rightly,
and cleanse your heart from all sin.
11 Offer a sweet-smelling sacrifice, and a memorial portion of choice flour,
and pour oil on your offering, as much as you can afford.
12 Then give the physician his place, for the Lord created him;
do not let him leave you, for you need him.
13 There may come a time when recovery lies in the hands of physicians,
14 for they too pray to the Lord
that he will grant them success in diagnosis
and in healing, for the sake of preserving life.
15 a man sins in the eyes of his Maker
if he defies the physician.
