10 “You shall sow your land for six years and gather in its yield, 11 but on the seventh year you shall let it rest and lie fallow, so that the needy of your people may eat; and whatever they leave the beast of the field may eat. You are to do the same with your vineyard and your olive grove.
12 “Six days you are to do your work, but on the seventh day you shall cease from labor so that your ox and your donkey may rest, and the son of your female slave, as well as your stranger, may refresh themselves. 13“Now concerning everything which I have said to you, be on your guard; and do not mention the name of other gods, nor let them be heard from your mouth.
God knew the allure and the enticement of serving ‘other gods’. It seems that whatever you aren’t doing is always more fun then what you have been doing. So God warned them not to even talk about or mention the name of other gods. If you talk about something, you can start dwelling on it. And if you do that, pretty soon it will lure you in, and you can let down your guard much easier. So focus on God, the one true God, and stay on the path He has set for you.
