and they became a bitterness of spirit to Isaac and to Rebekah. Bible

“a bitterness of spirit.” This is the use of “spirit” (Hebrew: ruach #07307 רוּחַ) that refers to the activities of the mind: the thoughts, attitudes and emotions. Esau’s Hittite wives caused bitter thoughts and attitudes in Isaac and Rebekah. [For more on the uses of “spirit,” see Appendix 6, “Usages of ‘Spirit.’” Usage #13 concerns thoughts and emotions].
