The law required only one fast in the year, that on the great day of Atonement (Lev 16:29; Num 29:7); though public memorial fasts were added, during the Captivity, on the anniversaries of national calamities. The Pharisees fasted every Monday and Thursday during the weeks between the Passover and Pentecost, and again between the Feast of Tabernacles and that of the Dedication of the Temple.
I give tithes (ἀποδεκατῶ)
See on Mat 23:23.
Possess (κτῶμαι)
Wrong. The Israelite did not pay tithes of his possessions, but only of his gains - his annual increase. See Gen 28:22; Deu 14:22. Besides, the verb, in the present tense, does not mean to possess, but to acquire; the meaning possess being confined to the perfect and pluperfect. Rev., get. Compare Mat 10:9 (Rev.); Act 22:28; Luk 21:19 (on which see note); 1Th 4:4 (Rev.).
