Is There A Scripture In The Bible That Speaks To The Heart Of An Individual Who Feels Mislead And Ultimately Abandoned By Someone They Trusted And Deeply Cared About?

The Song Of Psalms, in the Old Testament is primarily of King David while being pursued by King Herod who wanted to kill him. While this is not scripture as I believe that refers to the New Testament it is focus on betrayal and the hope of God and his salvation.

"Trust in the Lord with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge him, and he shall direct thy paths" (Proverbs 3:5-6). You can still trust the lord. So you still have it in there. However, you perhaps should not trust that person again. You can however trust someone else in time.

Joseph felt rejected, hurt and abandoned by his brothers when they threw him in the pit and sold him... However, because of his relationship in the Lord and deep trust, he was able to find forgiveness. Subsequently he would help them in time of need. This I believe is one of the many lessons that Father God desires for us to learn and appropriate in our life. God bless.
