Some suspect the first Creation account was written by people who believed in Elohim. From Genesis 1:1 to Genesis 2:3, the word אֱלֹהִ֑ים which is transliterated as Elohim and translated typically as God, is used in the Hebrew Bible in every verse of this Creation account except verses 13, 15, 19, 23 and 30 in the first Chapter. In Chapter 2, the only exceptions up to verse 4 is the first verse. In Genesis 2:4, the Hebrew word is introduced which gets transliterated typically as Yahweh. Some renders the expression as Jehovah, YHWH, JHWH and LORD.
The scriptures from Genesis 2:4 to the end of Genesis Chapter 3 appear to some people as transitory expressions to smooth out the the Elohist account (ones writing about Elohim) from the Yahwist account (ones writing about Yahweh). In these scriptures, the expression יְהוָ֥ה אֱלֹהִ֖ים is used which is transliterated as Yahweh Elohim and is typically translated as LORD God, Yahweh God and Jehovah God.
In Chapter 4, the expression for Yahweh, Jehovah or LORD is used singularly.
Happiness is the result of an enlightened mind whereas suffering is caused by a distorted mind.
