SEV Biblia, Chapter 11:13
Y será que, si escuchareis cuidadosamente mis mandamientos que yo os mando hoy, amando al SEÑOR vuestro Dios, y sirviéndole con todo vuestro corazón, y con toda vuestra alma,
John Gill's Bible Commentary
Ver. 13. And it shall come to pass, if you shall hearken diligently unto my commandments which I command you this day , etc.] In the name, and by the authority of the Lord, the only lawgiver: to love the Lord your God, and to serve him with all your heart, and with all your soul ; (see Deuteronomy 10:12). Jarchi interprets this of prayer; but it is not to be restrained to that only, but includes the whole service of God, in all the parts of it, performed from a principle of love to him, and in sincerity and truth.
Matthew Henry Commentary
Verses 8-17 - Moses sets before them, for the future, life and death, the blessin and the curse, according as they did or did not keep God's commandment Sin tends to shorten the days of all men, and to shorten the days of people's prosperity. God will bless them with an abundance of all goo things, if they would love him and serve him. Godliness has the promis of the life that now is; but the favour of God shall put gladness int the heart, more than the increase of corn, and wine, and oil. Revol from God to idols would certainly be their ruin. Take heed that you hearts be not deceived. All who forsake God to set their affection upo any creature, will find themselves wretchedly deceived, to their ow destruction; and this will make it worse, that it was for want of taking heed.
