When One Strengthens Himself He Receives Divine Strength

When One Strengthens Himself, He Receives Divine Strength:

Rav Dovid of Chernobyl said in the name of Zev Wolf of Zabriz zy”a that the meaning of the words “chazak, chazak, v’nischzek” is that when a Yid strengthens himself two times, he will be strengthened because Hashem will provide him with the strength to overcome all challenges.
