2) He said to them: I am now one hundred and twenty years old, I can no longer be active. Moreover, the LORD has said to me, “You shall not go across yonder Jordan.”
3) The LORD your God Himself will cross over before you; and He Himself will wipe out those nations from your path and you shall dispossess them.—Joshua is the one who shall cross before you, as the LORD has spoken.—

6) Be strong and resolute, be not in fear or in dread of them; for the LORD your God Himself marches with you: He will not fail you or forsake you.
7) Then Moses called Joshua and said to him in the sight of all Israel: “Be strong and resolute, for it is you who shall go with this people into the land that the LORD swore to their fathers to give them, and it is you who shall apportion it to them.
8) And the LORD Himself will go before you. He will be with you; He will not fail you or forsake you. Fear not and be not dismayed!”

And He charged Joshua son of Nun: “Be strong and resolute: for you shall bring the Israelites into the land that I promised them on oath, and I will be with you.”

6) “Be strong and resolute, for you shall apportion to this people the land that I swore to their fathers to assign to them.
7) But you must be very strong and resolute to observe faithfully all the Teaching that My servant Moses enjoined upon you. Do not deviate from it to the right or to the left, that you may be successful wherever you go.
8)Let not this Book of the Teaching cease from your lips, but recite it day and night, so that you may observe faithfully all that is written in it. Only then will you prosper in your undertakings and only then will you be successful.
9) “I charge you: Be strong and resolute; do not be terrified or dismayed, for the LORD your God is with you wherever you go.”

תָּנוּ רַבָּנַן: אַרְבָּעָה צְרִיכִין חִזּוּק, וְאֵלּוּ הֵן: תּוֹרָה, וּמַעֲשִׂים טוֹבִים, תְּפִלָּה, וְדֶרֶךְ אֶרֶץ.
תּוֹרָה וּמַעֲשִׂים טוֹבִים מִנַּיִן? — שֶׁנֶּאֱמַר:
״רַק חֲזַק וֶאֱמַץ מְאֹד לִשְׁמֹר וְלַעֲשׂוֹת כְּכׇל הַתּוֹרָה״, ״חֲזַק״ — בַּתּוֹרָה, ״וֶאֱמַץ״ — בְּמַעֲשִׂים טוֹבִים.
תְּפִלָּה מִנַּיִן? — שֶׁנֶּאֱמַר ״קַוֵּה אֶל ה׳ חֲזַק
וְיַאֲמֵץ לִבֶּךָ וְקַוֵּה אֶל ה׳״.
דֶּרֶךְ אֶרֶץ מִנַּיִן? — שֶׁנֶּאֱמַר ״חֲזַק וְנִתְחַזַּק בְּעַד עַמֵּנוּ וְגוֹ׳״.
Connected to the emphasis on the need to bolster one’s effort in prayer, the Gemara notes that the Sages taught in a baraita: Four things require bolstering, constant effort to improve, and they are: Torah, good deeds, prayer, and occupation.
For each of these, a biblical proof is cited: From where is it derived that Torah and good deeds require bolstering? As it is stated in the instruction to Joshua: “Only be strong and be extremely courageous, observe and do all of the Torah that Moses My servant commanded you; do not deviate to the right or to the left, that you may succeed wherever you go” (Joshua 1:7). In this verse, observe refers to Torah study and do refers to good deeds (Maharsha); the apparently repetitive language is not extraneous. The Gemara derives: Be strong in Torah and be courageous in good deeds.
From where is it derived that prayer requires bolstering? As it is said: “Hope in the Lord, strengthen yourself, let your heart take courage, and hope in the Lord.”
From where is it derived that occupation requires bolstering? As it is stated: “Be strong and we will be strong for the sake of our nation and for the cities of our God” (II Samuel 10:12). All of one’s labor requires bolstering.
