Regardeth. The four occurrences of the word in this verse are from the Gr. phronedo, here meaning “to observe,” “to esteem.” Compare Phil. 3:19; Col. 3:2, where phronedo is translated respectively “mind,” “set . . . affection on.”
Unto the Lord. The motive of both parties is the same, whether in the observance or neglect of a day, or in the use of, or abstinence from, food. The stronger brother thanks God for “all things” (v. 2) and partakes of his food to the glory of God (cf. 1 Cor. 10:31). His weaker brother thanks God for what he eats and to the glory of God abstains from foods that may have been sacrificed to idols (see on Rom. 14:1).
Regardeth not. Textual evidence favors (cf. p. 10) the omission of the clause, “and he that regardeth not the day, to the Lord he doth not regard it.” It is therefore omitted in modern versions. The meaning of the verse is left unchanged, for this clause simply presents, in the negative, the thought of the preceding clause.
Eateth not. See above under “unto the Lord.”
