Old Testament

The Book of Leviticus: Chapter 25:1-8-12

And the Lord spoke to Moses on Mount Sinai, saying, "Speak to the children of Israel, and say to them: 'When you come into the land which I give you, then the land shall keep a sabbath to the Lord. Six years you shall sow your field, and six years you shall prune your vineyard, and gather its fruit; but in the seventh year there shall be a sabbath of solemn rest for the land, a sabbath to the Lord. You shall neither sow your field nor prune your vineyard. What grows of its own accord of your harvest you shall not reap, nor gather the grapes of your untended vine, for it is a year of rest for the land. And the sabbath produce of the land shall be food for you: for you, your male and female servants, your hired man, and the stranger who dwells with you, for your livestock and the beasts that are in your land--all its produce shall be for food.

'And you shall count seven sabbaths of years for yourself, seven times seven years; and the time of the seven sabbaths of years shall be to you forty-nine years. Then you shall cause the trumpet of the Jubilee to sound on the tenth day of the seventh month; on the Day of Atonement you shall make the trumpet to sound throughout all your land. And you shall consecrate the fiftieth year, and proclaim liberty throughout all the land to all its inhabitants. It shall be a Jubilee for you; and each of you shall return to his possession, and each of you shall return to his family. That fiftieth year shall be a Jubilee to you; in it you shall neither sow nor reap what grows of its own accord, nor gather the grapes of your untended vine. For it is the Jubilee; it shall be holy to you; you shall eat its produce from the field.

New Testament

The Epistle to the Hebrews: Chapter 6:13-20

For when God made a promise to Abraham, because He could swear by no one greater, He swore by Himself, saying, "Surely blessing I will bless you, and multiplying I will multiply you." And so, after he had patiently endured, he obtained the promise. For men indeed swear by the greater, and an oath for confirmation is for them an end of all dispute. Thus God, determining to show more abundantly to the heirs of promise the immutability of His counsel, confirmed it by an oath, that by two immutable things, in which it is impossible for God to lie, we might have strong consolation, who have fled for refuge to lay hold of the hope set before us. This hope we have as an anchor of the soul, both sure and steadfast, and which enters the Presence behind the veil, where the forerunner has entered for us, even Jesus, having become High Priest forever according to the order of Melchizedek.
