Deuteronomy 6:13 Meaning and Commentary

Deuteronomy 6:13

Thou shalt fear the Lord thy God, and serve him
Serve him through fear; not through slavish fear, a fear of hell and damnation; but through filial fear, a reverential affection for that God that had brought them out of a state of bondage into great and glorious liberty, out of Egypt into Canaan's land, out of a place of misery into a land of plenty; and therefore should fear the Lord and his goodness, and from such a fear of him serve him, in every part of worship, public and private, enjoined; this passage Christ refers to ( Matthew 4:10 )

and shalt swear by his name;
when they made a covenant with any, or were called to bear a testimony for the decision of any controversy which could not be otherwise finished; or whenever they took an oath on any account, which should never be taken rashly or on any trivial account, and much less falsely; it should be taken not in the name of any idol, or of any other but the true and living God; the Targum of Jonathan is,

``in the name of the Word of the Lord, in truth ye shall swear.''

Deuteronomy 6:13 In-Context

11 and houses full of all good things which thou hast not filled, and wells digged which thou hast not digged, vineyards and olive-yards which thou hast not planted, and thou hast eaten, and been satisfied;
12 `Take heed to thyself lest thou forget Jehovah who hath brought thee out of the land of Egypt, out of a house of servants;
13 Jehovah thy God thou dost fear, and Him thou dost serve, and by His name thou dost swear;
14 ye do not go after other gods, of the gods of the peoples who [are] round about you;
15 for a zealous God [is] Jehovah thy God in thy midst -- lest the anger of Jehovah thy God burn against thee, and He hath destroyed thee from off the face of the ground.
