Insiders and outsiders

Then you shall call, and the Lord will answer; you shall cry for help, and he will say, Here I am. If you remove the yoke from among you, the pointing of the finger, the speaking of evil, if you offer your food to the hungry and satisfy the needs of the afflicted, then your light shall rise in the darkness and your gloom be like the noonday. The Lord will guide you continually, and satisfy your needs in parched places, and make your bones strong; and you shall be like a watered garden, like a spring of water, whose waters never fail. Your ancient ruins shall be rebuilt; you shall raise up the foundations of many generations; you shall be called the repairer of the breach, the restorer of streets to live in.

If you refrain from trampling the sabbath, from pursuing your own interests on my holy day; if you call the sabbath a delight and the holy day of the Lord honorable; if you honor it, not going your own ways, serving your own interests, or pursuing your own affairs; then you shall take delight in the Lord, and I will make you ride upon the heights of the earth; I will feed you with the heritage of your ancestor Jacob, for the mouth of the Lord has spoken.

Luke 5:27-32

After this he went out and saw a tax collector named Levi, sitting at the tax booth; and he said to him, “Follow me.” And he got up, left everything, and followed him. Then Levi gave a great banquet for him in his house; and there was a large crowd of tax collectors and others sitting at the table with them. The Pharisees and their scribes were complaining to his disciples, saying, “Why do you eat and drink with tax collectors and sinners?” Jesus answered, “Those who are well have no need of a physician, but those who are sick; I have come to call not the righteous but sinners to repentance.”
