John Lightfoot on Luke 1:6

[In all the commandments and ordinances, &c.] So Numbers 36:13, These are the commandments and judgments. It would perhaps seem a little too fine and curious to restrain the commandments to the decalogue, or ten commandments, and the ordinances to the ceremonial and judicial laws, though this does not wholly want foundation. It is certain the precepts delivered after the decalogue, from Exodus 21 to chapter 24, are called judgments, or ordinances, Exodus 21:1, 24:3.

The Vulgar can hardly give any good account why he should render ordinances by justifications, much less the followers of that translation why they should from thence fetch an argument for justification upon observation of the commands, when the commands and institutions of men are by foreign authors called ordinances; nay, the corrupt customs that had been wickedly taken up have the same word, 1 Samuel 2:13, the priest's 'custom' with the people was, &c. 2 Kings 17:8, and walked in the 'statutes' of the heathen

The word ordinance is frequently rendered by those interpreters from ordain; which, to wave all other instances, may abundantly appear from Psalm 119. And the very things which the Jews speak of the Hebrew word obtain also in the Greek.

"Perhaps Satan and the Gentiles will question with Israel, what this or that command means, and what should be the reason of it. The answer that ought to be made in this case is, It is ordained, it is a law given by God, and it becomes not thee to cavil."

"Ye shall observe my statutes, [Lev 18:4] that is, even those which Satan and the nations of the world do cavil at. Such are those laws about eating swine's flesh; heterogeneous clothing; the nearest kinsman's [leviri] putting off the shoe; the cleansing of the leper, and the scapegoat. If, perhaps, it should be said that these precepts are vain and needless, the text saith, 'I am the Lord. I, the Lord, have ordained these things; and it doth not become thee to dispute them.'" They are ordinances, just and equal, deriving their equity from the authority of him that ordained them.
