Deuteronomy 10:18

"He doth execute justice for the fatherless and the widow, and loveth the sojourner, in giving him food and raiment. Love ye therefore the sojourner; for ye were sojourners in the land of Egypt. Thou shalt fear Jehovah thy God; him thou shalt serve; and to him thou shalt cleave, and by his name shalt thou sware. He is thy praise, and he is thy God, that hath done for thee these great and terrible things, which thine eyes have seen. Thy fathers went down into Egypt with threescore and ten persons; and now Jehovah thy God hath made thee as the stars of heaven for multitude."

As Cousins noted, "God's people are still thought of as being "foreigners."[29] There are several Biblical words used in reference to this quality of being citizens not of this world, but of another. They are: strangers, foreigners, pilgrims, sojourners, etc. Paul's famous passage, "Our citizenship is in heaven ..." etc. (Philippians 3:20) is based upon this conception. All such expressions eventually refer back to Abraham who dwelt in tents but never owned any land in Canaan except a burial place. When one thinks of the great wealth of the patriarchs, it is still astonishing that none of them ever built a house. They accepted for themselves the status of "pilgrims and sojourners." The word "pilgrim," especially, catches the sentiment of this. Pilgrim actually and literally means "one who crosses the field," and it came into use during the Crusades, when all across Europe, it was nothing unusual for settled citizens to see a lonely traveler crossing a field or a clearing on the way to the Holy Land. The word came to have a sacred connotation for one who, leaving all secondary considerations behind, pressed onward to the achievement of some sacred goal. In this connection also, we remember that the orthodox Jew today never actually completes his residence, but leaves a token part of it unfinished.

"Thou shalt fear Jehovah thy God, and him shalt thou serve ..." (Deuteronomy 10:20). Dummelow pointed out that this was one of the replies that Jesus made to Satan in the Temptation.[30]

"Deuteronomy 10:21-22 are a summary of all that has just been said."[31] What is taught is that the total devotion of the whole life should be to the service of God. It is God to whom one must cleave. "The Hebrew word here for `cleave' means `to cling to' or `hold fast to' with warm affection."[32] "`He is your praise' means he is the sole object of your praise."[33]
