Psalm 119:32 "I will run the way of thy commandments, when thou shalt enlarge my heart."
This verse jumped out at me because I had read about how long-distance runners sometimes literally get an enlarged heart.
From Wikipedia: "Athletic heart syndrome, (AHS) also known as athlete's heart,[1][2] athletic bradycardia or exercise-induced cardiomegaly is a non-pathological condition commonly seen in sports medicine, in which the human heart is enlarged, and the resting heart rate is lower than normal.
"Athlete's heart is common in athletes who routinely exercise more than an hour a day, and occurs primarily in endurance athletes, though it can occasionally arise in heavy weight trainers. The condition is generally believed to be a benign one..."
Obviously the Bible verse is figurative, but it is interesting that it parallels a real, physical condition.
The Bible is always scientifically right on!
