Verses with the word race in the Old Testament (2 verses):

Psalms 19:5
Which is as a bridegroom coming out of his chamber, and rejoiceth as a strong man to run a race.

Ecclesiastes 9:11
I returned, and saw under the sun, that the race is not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favour to men of skill; but time and chance happeneth to them all.
