He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities.
Travail: (Strong’s and Gesenius' Hebrew-Chaldee Lexicon) weariness, trouble, vexation, (and as to Isaiah 53:11) of the sorrow (or anguish) of his soul.
The same Hebrew word and meaning are in the following passages:
And Joseph called the name of the firstborn Manasseh: For God, said he, hath made me forget all my toil (weariness, trouble, vexation), and all my father's house.
And when we cried unto the Lord God of our fathers, the Lord heard our voice, and looked on our affliction, and our labour (weariness, trouble, vexation), and our oppression:
1 Then Job answered and said,
2 I have heard many such things: miserable (weariness, trouble, vexation), comforters are ye all.
Peter discusses the vexation of Lot in the New Testament:
2 Peter 2:7,8
7 And delivered just Lot, vexed with the filthy conversation of the wicked:
8 (For that righteous man dwelling among them, in seeing and hearing, vexed his righteous soul from day to day with their unlawful deeds;)
Isaiah 59:15 states
Yea, truth faileth; and he that departeth from evil maketh himself a prey: and the Lord saw it, and it displeased him that there was no judgment.
I departed from evil and made myself a prey. My soul has been vexed just like Lot’s by the filthy conversation and unlawful deeds of the wicked. Certainly God’s people have treated me like Job’s friends treated him.
Now the good part; God caused Joseph to forget all his toil (weariness, trouble, vexation), and I expect God to make me forget all my toil and I will say as Paul did,
From henceforth let no man trouble me:
I give God all the praise and glory!
Servant and apostle of the Lord Jesus Christ
