For though their words were good, their heart with him was not sincere; Unstedfast and perfidious they in his cov'nant were.
And might not, like their fathers, be a stiff rebellious race; A race not right in heart; with God whose sp'rit not stedfast was.
Create a clean heart, Lord, renew a right sp'rit me within.
My heart let in thy laws be sound, that sham'd I never be.
