Matthew 11:28-30 (NLT)
Then Jesus said, “Come to me, all of you who are weary and carry heavy burdens, and I will give you rest.  29  Take my yoke upon you. Let me teach you, because I am humble and gentle at heart, and you will find rest for your souls. 30  For my yoke is easy to bear, and the burden I give you is light.”

Genesis 25:24-34 (NIV)
When the time came for her to give birth, there were twin boys in her womb. 25  The first to come out was red, and his whole body was like a hairy garment; so they named him Esau.  26  After this, his brother came out, with his hand grasping Esau’s heel; so he was named Jacob. Isaac was sixty years old when Rebekah gave birth to them. 27  The boys grew up, and Esau became a skillful hunter, a man of the open country, while Jacob was content to stay at home among the tents.  28  Isaac, who had a taste for wild game, loved Esau, but Rebekah loved Jacob. 29  Once when Jacob was cooking some stew, Esau came in from the open country, famished.  30  He said to Jacob, “Quick, let me have some of that red stew! I’m famished!” (That is why he was also called Edom.) 31  Jacob replied, “First sell me your birthright.” 32  “Look, I am about to die,” Esau said. “What good is the birthright to me?” 33  But Jacob said, “Swear to me first.” So he swore an oath to him, selling his birthright to Jacob. 34  Then Jacob gave Esau some bread and some lentil stew. He ate and drank, and then got up and left. So Esau despised his birthright.

Hebrews 6:13-20 (NLT)
For example, there was God’s promise to Abraham. Since there was no one greater to swear by, God took an oath in his own name, saying: 14  “I will certainly bless you, and I will multiply your descendants beyond number.” 15  Then Abraham waited patiently, and he received what God had promised. 16  Now when people take an oath, they call on someone greater than themselves to hold them to it. And without any question that oath is binding.  17  God also bound himself with an oath, so that those who received the promise could be perfectly sure that he would never change his mind.  18  So God has given both his promise and his oath. These two things are unchangeable because it is impossible for God to lie. Therefore, we who have fled to him for refuge can have great confidence as we hold to the hope that lies before us.  19  This hope is a strong and trustworthy anchor for our souls. It leads us through the curtain into God’s inner sanctuary.  20  Jesus has already gone in there for us. He has become our eternal High Priest in the order of Melchizedek.
