International Standard Version One person decides in favor of one day over another, while another person decides that all days are the same. Let each one be fully convinced in his own mind:
American Standard Version One man esteemeth one day above another: another esteemeth every day alike . Let each man be fully assured in his own mind.
Young's Literal Translation One doth judge one day above another, and another doth judge every day alike; let each in his own mind be fully assured.
