What the Holy Bible says about Rest:

28 “Come to me, all you who are weary and burdened, and I will give you rest. 29 Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. 30 For my yoke is easy and my burden is light.” (Matthew 11: 28-30)

Thus the heavens and the earth were completed in all their vast array. By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work. Then God blessed the seventh day and made it holy, because on it he rested from all the work of creating that he had done. This is the account of the heavens and the earth when they were created, when the Lord God made the earth and the heavens. (Genesis 2: 1-4)

Be still before the Lord and wait patiently for him. (Psalm 37: 7)

Return to your rest, my soul, for the Lord has been good to you. (Psalm 116: 7)
