For he that is entered into his rest, he also hath ceased from his own works, as God did from his. For he that is entered into his rest - The man who has believed in Christ Jesus has entered into his rest; the state of happiness which he has provided, and which is the forerunner of eternal glory.
Hath ceased from his own works - No longer depends on the observance of Mosaic rites and ceremonies for his justification and final happiness. He rests from all these works of the law as fully as God has rested from his works of creation.
Those who restrain the word rest to the signification of eternal glory, say, that ceasing from our own works relates to the sufferings, tribulations, afflictions, etc., of this life; as in Revelation 14:13. I understand it as including both.
In speaking of the Sabbath, as typifying a state of blessedness in the other world, the apostle follows the opinions of the Jews of his own and after times. The phrase שבת עלאה ושבת התאה shabbath illaah, veshabbath tethaah, the sabbath above, and the sabbath below, is common among the Jewish writers; and they think that where the plural number is used, as in Leviticus 19:30 : Ye shall keep my Sabbaths, that the lower and higher sabbaths are intended, and that the one is prefigured by the other. See many examples in Schoettgen.
