The King James Bible addresses rest in several passages:
Matthew 11:28-30 (KJV)
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.
Genesis 2:2-3 (KJV)
2 And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made. 3 And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.
Exodus 20:8-10 (KJV)
8 Remember the sabbath day, to keep it holy. 9 Six days shalt thou labour, and do all thy work: 10 But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
Psalms 23:1-3 (KJV)
1 The LORD is my shepherd; I shall not want. 2 He maketh me to lie down in green pastures: he leadeth me beside the still waters. 3 He restoreth my soul: he leadeth me in the paths of righteousness for his name’s sake.
Hebrews 4:9-10 (KJV)
9 There remaineth therefore a rest 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.
