I. A solemn charge given to the people of God not to conform themselves to the ways and customs of the heathen. Let the house of Israel hear and receive this word from the God of Israel: "Learn not the way of the heathen, do not approve of it, no, nor think indifferently concerning it, much less imitate it or accustom yourselves to it. Let not any of their customs steal in among you (as they are apt to do insensibly) nor mingle themselves with your religion." Note, It ill becomes those that are taught of God to learn the way of the heathen, and to think of worshipping the true God with such rites and ceremonies as they used in the worship of their false gods. See Deut. xii. 29-31. It was the way of the heathen to worship the host of heaven, the sun, moon, and stars; to them they gave divine honours, and from them they expected divine favours, and therefore, according as the signs of heaven were, whether they were auspicious or ominous, they thought themselves countenanced or discountenanced by their deities, which made them observe those signs, the eclipses of the sun and moon, the conjunctions and oppositions of the planets, and all the unusual phenomena of the celestial globe, with a great deal of anxiety and trembling. Business was stopped if any thing occurred that was thought to bode ill; if it did but thunder on their left hand, they were almost as if they had been thunderstruck. Now God would not have his people to be dismayed at the signs of heaven, to reverence the stars as deities, nor to frighten themselves with any prognostications grounded upon them. Let them fear the God of heaven, and keep up a reverence of his providence, and then they need not be dismayed at the signs of heaven, for the stars in their courses fight not against any that are at peace with God. The heathen are dismayed at these signs, for they know no better; but let not the house of Israel, that are taught of God, be so.
