“This day the LORD thy God hath commanded thee to do these statutes and judgments: thou shalt therefore keep and do them with all thine heart, and with all thy soul.”
King James Version (KJV)
26:14 In my mourning - In sorrow, or grieving that I was to give away so much of my profits to the poor, but I have chearfully eaten and feasted with them, as I was obliged to do. Unclean use - For any common use; for any other use than that which thou hast appointed, which would have been a pollution of them. For the dead - For any funeral pomp or service; for the Jews used to send in provisions to feast with the nearest relations of the party deceased; and in that case both the guests and food were legally polluted, #Num 19:11|,14, and therefore the use of these tithes in such cases had been a double fault, both the defiling of sacred food, and the employing those provisions upon sorrowful occasions, which by God's express command were to be eaten with rejoicing.
26:15 Look down - After that solemn profession of their obedience to God's commands, they are taught to pray for God's blessing whereby they are instructed how vain and ineffectual the prayers of unrighteous or disobedient persons are.
26:17 Avouched - Or, declared, or owned.
26:18 Avouched thee - Hath owned thee for such before all the world by eminent and glorious manifestations of his power and favour, by a solemn entering into covenant with thee, and giving peculiar laws, promises, and privileges to thee above all mankind.
