Matthew 11:28-30
(28) Come unto me, all ye that labour and are heavy laden, and I will give you rest.
(29) Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.
(30) For my yoke is easy, and my burden is light.
Hebrews 4:9-11
(9) There remaineth therefore a rest (G4520) to the people of God.
(10) For he that is entered into his rest, he also hath ceased from his own works, as God did from his.
(11) Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief.
G4520
σαββατισμός
sabbatismos
sab-bat-is-mos'
