Luke 1:73

The oath. The “oath” here referred to was that given by God in confirmation of His covenant with Abraham (see Gen. 22:16-18; Heb. 6:13-18). It is one of the two “immutable things, in which it was impossible for God to lie” (Heb. 6:18), the other being the promise which the “oath” confirms. In giving Abraham “an oath for confirmation” God employed a human custom in order to assure Abraham of the certainty of His promise. The everlasting covenant, the plan of salvation, gives us today “a strong consolation” and is “as an anchor of the soul, both sure and stedfast” (Heb. 6:18, 19).
