A merry heart doeth good like a medicine: but a broken spirit drieth the bones.
Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.
All the days of the afflicted are evil: but he that is of a merry heart hath a continual feast.
A sound heart ils the life of the flesh: but envy the rottenness of the bones.
But godliness with contentment is greater gain.
1 Timothy 6:6
Let not thine heart envy sinners: but be thou in the fear of the Lord all the day long. For surely there is an end; and thine expectation shall not be cut off.
