SEV Biblia, Chapter 23:6
Esforzaos pues mucho a guardar y hacer todo lo que está escrito en el libro de la ley de Moisés, sin apartaros de ello ni a la diestra ni a la siniestra;
Clarke's Bible Commentary - Joshua 23:6
Verse 6. Be ye therefore very courageous to keep and to do, &c.] It requires no small courage to keep a sound creed in the midst of scoffers, and not less to maintain a godly practice among the profane and profligate. That is written in the book] By the word of God alone his followers are bound. Nothing is to be received as an article of faith which God has not spoken.
John Gill's Bible Commentary
Ver. 6. Be ye therefore very courageous to keep and to do all that is written in the book of the law of Moses , etc.] To observe which required spiritual strength, fortitude of mind, a holy courage, a firm and fixed resolution, and particularly to destroy the Canaanites required in that book, and to abstain from all communion and fellowship with them: that ye turn not aside therefrom, [to] the right hand or the left ; (see Gill on “ Joshua 1:7”).
Matthew Henry Commentary
Verses 1-10 - Joshua was old and dying, let them observe what he said now. He pu them in mind of the great things God had done for them in his days. He exhorted them to be very courageous. Keep with care, do with diligence and regard with sincerity what is written. Also, very cautiously to endeavour that the heathen idolatry may be forgotten, so that it ma never be revived. It is sad that among Christians the names of the heathen gods are so commonly used, and made so familiar as they are Joshua exhorts them to be very constant. There might be many thing amiss among them, but they had not forsaken the Lord their God; the way to make people better, is to make the best of them.
