Deuteronomy 6:16-18

16Do not put the LORD your God to the test as you did at Massah. 17Be sure to keep the commands of the LORD your God and the stipulations and decrees he has given you. 18Do what is right and good in the LORD ’s sight, so that it may go well with you and you may go in and take over the good land the LORD promised on oath to your ancestors,
