Kith was used in Angela's Ashes: A Memoir as a way of describing the feeling of relational loneliness. Even the dog was gone.
In Scripture, Abraham's life was an example of one who left kith and kin to follow God.
It's faith at its best. Faith might not know where God's leading will take them but knowing the One who is leading provides the faith and assurance needed to go.
Kith, without Kin, is an old English word for friends and neighbors.
For me, the Kin part reminds me of kin as related by blood in family or by adoption. Kin can also include believers in fellowship---one's church family! Think "heart" family!
But God, in His love and mercy, has shown me the necessity of connection through the blood of Christ regardless if the mileage separation! I have greatly experienced that KIN in our recent move.
I would have been dismayed if I had not seen the goodness of the LORD in the land of the living. (Psalm 27:13)
Kith and Kin are my land of the living!
