Luke 18:12

I fast twice in the week, I give tithes of all that I possess.

I fast twice in the week, I give tithes (or the tenth) of all that I possess, [ ktoomai (G2932)] - or 'acquire;' 'of all my gains' or 'increase.' Not confining himself to the one divinely prescribed annual fast (Leviticus 16:29), he was not behind the most rigid, who, as Lightfoot says, fasted on the second and fifth days of every week, and gave the tenth not only of what the law laid under tithing, but of "all his gains." Thus, besides doing all his duty, he did works of supererogation; while sins to confess and spiritual wants to be supplied he seems to have felt none. What a picture of the Pharisaic character and religion!
