PROLOGUE — From Conqueror to Preacher
Joshua 23 records the first farewell sermon of the great leader who led the conquest, now old and advanced in years, delivered before the whole leadership of Israel. This sermon follows a pattern remarkably similar to that shown by Moses in Deuteronomy — looking back on the past, and warning of the future.
ACT ONE — The LORD Your God Fought for You (verses 1–5)

“And it came to pass a long time after that the LORD had given rest unto Israel from all their enemies round about, that Joshua waxed old and stricken in age. And Joshua called for all Israel, and for their elders, and for their heads, and for their judges, and for their officers… I am old and stricken in age: And ye have seen all that the LORD your God hath done unto all these nations because of you; for the LORD your God is he that hath fought for you.”
For the LORD your God is he that hath fought for you. Joshua did not boast in his own military achievements — he attributed all credit for victory entirely to God. This was the spirit of humility that ran through the whole of his leadership.
ACT TWO — Turn Not Aside to the Right Hand or to the Left (verses 6–8)
Joshua urged obedience, directly echoing the language of Deuteronomy.
“Be ye therefore very courageous to keep and to do all that is written in the book of the law of Moses, that ye turn not aside therefrom to the right hand or to the left… But cleave unto the LORD your God, as ye have done unto this day.”

Cleave unto him as ye have done unto this day. He acknowledged their past faithfulness, while emphasizing that it had to continue into the future.
ACT THREE — One Man of You Shall Chase a Thousand (verses 9–13)
Joshua reminded them of the supernatural victories Israel had experienced.
“For the LORD hath driven out from before you great nations and strong: but as for you, no man hath been able to stand before you unto this day. One man of you shall chase a thousand: for the LORD your God, he it is that fighteth for you.”
One man of you shall chase a thousand. This was a dramatic expression emphasizing that Israel’s military success was never their own capability, but entirely God’s own intervention.
But this victory was conditional — Joshua immediately shifted into warning.
“Else if ye do in any wise go back, and cleave unto the remnant of these nations… and shall make marriages with them… know for a certainty that the LORD your God will no more drive out any of these nations from before you; but they shall be snares and traps unto you, and scourges in your sides, and thorns in your eyes, until ye perish from off this good land.”
Snares and traps… scourges… thorns. This warning precisely echoes imagery already used in Deuteronomy 33, vividly foreseeing the future danger that incomplete conquest would bring.
ACT FOUR — Good Words and Words of Calamity, the Same Certainty (verses 14–16)
Joshua’s sermon closes with a remarkably balanced conclusion.
“And, behold, this day I am going the way of all the earth: and ye know in all your hearts and in all your souls, that not one thing hath failed of all the good things which the LORD your God spake concerning you; all are come to pass unto you, and not one thing hath failed thereof… If ye transgress the covenant of the LORD your God, which he commanded you, and go and serve other gods… then shall the anger of the LORD be kindled against you, and ye shall perish quickly from off the good land.”
Not one thing hath failed of the good things… the words of calamity likewise. Joshua reflects exactly the fulfillment already proclaimed in chapter 21 — that not one of God’s good promises had failed — while simultaneously warning that this very same certainty would apply equally to the curse.
REFLECTION — A Warning Given at the Moment of Victory
The insight Joshua 23 gives us is that the moment of greatest victory is precisely when a warning toward the future is most needed. At the very point when the conquest was complete and the land settled, Joshua called not for complacency, but for continued vigilance.
Even when life is stable and going smoothly, do you continue to maintain the tension of ongoing obedience toward God?
