Yehoshua 1:6-7

6 Chazak! (be strong!) And be of good courage: for unto HaAm Hazeh shalt thou divide for a nachalah HaAretz, which I swore unto their avot to give them.

7 Only chazak (be strong) and very courageous, that thou mayest be shomer to do according to kol HaTorah, which Moshe Avdi commanded thee; turn not from it to the yamin or to the semol, in order that thou mayest succeed everywhere thou goest.

Yehoshua 1:9

9 Have not I commanded thee? Chazak! And be of good courage; be not afraid, neither be thou dismayed; for Hashem Eloheicha is with thee everywhere thou goest.

Yehoshua 1:18

18 Whosoever he be that doth rebel against thy commandment, and will not pay heed unto thy devarim in all that thou commandest him, he shall be put to death; rak chazak (only be strong) and be of good courage.
