We could call this section Like Father, Like Son. Isaac built his wealth and was blessed by God, and promised that his offspring would possess the nations they were living in. He redug wells that Abraham had dug and gave them the same names. But this chapter begins with Isaac lying to Abimelech about his wife being his sister. Abraham not only did that twice, and got caught both times, but one of the kings he did it to was Abimelech.
