(9) Open . . .--A condensed statement of God's gracious promise (Deuteronomy 7:12-13; Deuteronomy 8:7; Deuteronomy 8:9; Deuteronomy 11:13; Deuteronomy 11:16, &c). It is said to have been a custom in Persia, that when the king wishes to do a visitor especial honour he desires him to open his mouth wide, and the king then-crams it full of sweetmeats, and sometimes even with jewels. And to this day it is a mark of politeness in Orientals to tear off the daintiest bits of meat for a guest, and either lay them before him, or put them in his mouth. (See Thomson, Land and Book, p. 127.)

Verse 9. - There shall no strange god be in thee; neither shalt thou worship any strange god (comp; Exodus 20:3; Deuteronomy 5:7). Such worship had evidently begun, and required to be forbidden afresh.

81:8-16 We cannot look for too little from the creature, nor too much from the Creator. We may have enough from God, if we pray for it in faith. All the wickedness of the world is owing to man's wilfulness. People are not religious, because they will not be so. God is not the Author of their sin, he leaves them to the lusts of their own hearts, and the counsels of their own heads; if they do not well, the blame must be upon themselves. The Lord is unwilling that any should perish. What enemies sinners are to themselves! It is sin that makes our troubles long, and our salvation slow. Upon the same conditions of faith and obedience, do Christians hold those spiritual and eternal good things, which the pleasant fields and fertile hills of Canaan showed forth. Christ is the Bread of life; he is the Rock of salvation, and his promises are as honey to pious minds. But those who reject him as their Lord and Master, must also lose him as their Saviour and their reward.There shall no strange god be in thee,.... Or in the midst of thee, owned and worshipped as God; or in thine heart, for whatever engrosses the affection, or a man puts his trust and confidence in, that he makes his god, and is a strange one: thus, if any friend or relation, father or mother, wife or children, are loved more than God, they are set up as such in his place; thus the epicure, that seeks the gratification of his carnal lusts, makes his belly his god; and the covetous man his money, in which he trusts, and therefore is called an idolater; and the self-righteous man his righteousness, on which he depends for salvation: hence we read of idols set up in the heart, from which they are disengaged in conversion, and kept from, Ezekiel 14:7.

neither shall thou worship any strange god; only the Lord God is to be worshipped, Matthew 28:19 and there is but one God; though this is to be understood not to the exclusion of the Son and Spirit, who are with the Father the one God, and to be worshipped equally with him, and are; see Matthew 28:19.
