This is very significant. God gave the land to the other tribes but He gave Himself to the Levites. There is such a thing in Christian life as an inheritance from the Lord, and there is such a thing as having the Lord Himself for our inheritance.
Some people get a sanctification from the Lord which is of much value, but which is variable, and often impermanent. Others have learned the higher lesson of taking the Lord Himself to be their keeper and their sanctity, and abiding in Him they are kept above the vicissitudes of their own states and feelings.
Some get from the Lord large measures of joy and blessing, and times of refreshing.
Others, again, learn to take the Lord Himself as their joy.
Some people are content to have peace with God, but others have taken "the peace of God that passeth all understanding."
Some have faith in God, while others have the faith of God. Some have many touches of healing from God, others, again, have learned to live in the very health of God Himself.
