If it seem evil; unjust, unreasonable, or inconvenient. Choose you this day whom ye will serve: not that he leaves them to their liberty, whether they would serve God or idols; for Joshua had no such power or liberty himself, nor could give it to any other; and both he and they were obliged by the law of Moses to give their worship to God only, and to forbear all idolatry in themselves, and severely to punish it in others; but it is a rhetorical and powerful insinuation, whereby he both implies that the worship of God is so highly reasonable, so necessary and beneficial, and the service of idols is so absurd, and vain, and pernicious, that if it were left free to all men to make their choice, every man in his right wits must needs choose the service of God before that of idols; and provokes them to bind themselves faster to God by their own choice. See such manner of speeches in Ruth 1:8,15 1 Kings 18:21. But as for me and my house, we will serve the Lord; but know this, if you should all be so base and brutish, as to prefer senseless and impotent idols before the true and living God, it is my firm purpose, that I will, and my children and servants (as far as I can influence them) shall, be constant and faithful to the Lord.

15 And if it seem evil unto you to serve the LORD, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the LORD.
