John Calvin on Deuteronomy 16:21

21. Thou shalt not plant thee. It is plain from the end of this verse that it is part of the Second Commandment. We know See Lucian in Dea Syria, sub initium; Πρῶτοι μὲν ὦν ἀνθρώπων, τῶν ἡμεῖς ἴδμεν, Αἰγύπτιοι λέγονται θεῶν τε ἐννοίαν λαβεὶν, καὶ ἱρὰ εἴσασθαι, καὶ τεμένεα, κ. τ. λ., — Tacitus Germ. 9. “Lucos et nemora consecrant.” Virgil. Eccl. 6:73. “Ne quis sit lucus, quo plus se jactet Apollo." that amongst the heathen nations groves were sacred, so that with them no religious object would receive due reverence, except under the shade of trees. Wherefore lest conformity with this general custom should vitiate the pure worship of God, this distinction was made; and this then is the intent of the prohibition, that the Jews should fly from all strange rites, lest by too closely approaching the Gentiles, they should introduce a sinful medley. But how necessary this prohibition was, appears from their eager imitation (of the heathen), of which mention is constantly made in the sacred history. For there was scarcely any period in which they abstained from “high places.” Nor is it without reason that Isaiah and Jeremiah reprove them for “playing the harlot under every green tree.” (Isaiah 57:5; Jeremiah 2:20; 3:6.)

Exodus 34

Exodus 34:11, 12, 15, 16

11. Observe thou that which I command thee this day: behold, I drive out before thee the Amorite, and the Canaanite, and the Hittite, and the Perizzite, and the Hivite, and the Jebusite.

11. Custodi quod ego praecipio tibi hodie. Ecce ego ejiciam a facie tua Amorrhaeum, Chananaeum, Hittaeum, Pheresaeum, Hivaeum, et Jebusaeum.

12. Take heed to thyself, lest thou make a covenant with the inhabitants of the land whether thou goest, lest it be for a snare in the midst of thee:

12. Cave tibi ne forte percutias foedus cum habitatoribus ejus terrae ad quam ingressurus es, ne forte sint in laqueum vel offendiculum in medio tui.

15. Lest thou make a covenant with the inhabitants of the land, and they go a whoring after their gods, and do sacrifice unto their gods, and one call thee, and thou eat of his sacrifice;

15. Ne forte percutias foedus cum habitatoribus ejus terrae, ut scortentur post deos suos, et sacrificent diis suis: vocet autem to quispiam, et comedas e sacrificio ejus.

16. And thou take of their daughters unto thy sons, and their daughters go a whoring after their gods, and make thy sons go a whoring after their gods.

16. Et forte accipias e filiabus ejus filiis tuis, et scortentur filiae ejus post deos ipsarum, et scortari faciant filios tuos post deos earum.

Exodus 23

Exodus 23:31-33

31. ... for I will deliver the inhabitants of the land into your hand; and thou shalt drive them out before thee.

31. Dabo in manum vestram habitatores terrae, et expelles cos a facie tua.

32. Thou shalt make no covenant with them, nor with their gods.

32. Non percuties cum ipsis foedus, nec cum diis eorum.

33. They shall not dwell in thy land, lest they make thee sin against me: for if thou serve their gods, it will surely be a snare unto thee.

33. Non habitabunt in terra tua: ne forte peccare faciant te contra me quando colueris deos eorum, quod erit tibi in offendiculum.
