Question: Was Adam with Eve when she spoke to the serpent (Genesis 3:6)?”
*The Bible indicates that Eve was the first to eat of the forbidden fruit, after she was deceived by the serpent.
*Your question is in two parts:
1) Where was Adam when Eve was holding her conversation with the serpent? and
2) Was he physically with Eve when she and the serprent were conversing?
“When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable for gaining wisdom, she took some and ate it. She also gave some to her husband, who was with her, and he ate it.” (Genesis 3:6, NIV)
The key phrase in looking at the question is “who was with her.” Traditional Jewish interpretation takes this phrase to mean that Adam was with Eve the whole time she was being tempted and that he heard the whole conversation.
The understanding helps to explain the emphasis on “Adam’s sin” in the New Testament (Romans 5:12). “Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned—” (Romans 5:12, NKJV).
Adam was created first and placed in the Garden of Eden to care for it along with Eve. Adam then actively participated in breaking the one rule God gave him to obey. If Adam had not been present when Eve spoke with the serpent, it would be more difficult to understand why the first sin is emphasized as being Adams.
Another view that one must wrestle with is that the phrase “who was with her” simply means that Adam was with Eve when she offered him the fruit. In other words, Eve heard the serpent’s lies (was deceived by him) believed they were the truth and ate the fruit. Then she found her husband, and once she had him “with her,” she gave him the fruit, too.
This understanding would explain why Adam did not intervene in the serpent’s deception of Eve and why the New Testament insists that Eve as “deceived” but Adam was not (I Timothy 2:14). The fact that death came through Adam’s sin instead of Eve’s is explained by the idea that the federal headship of mankind was vested in Adam, as the one first created (I Timothy 2:13).
Of course, there is a third view, that Adam was in the vicinity of the tree while Eve was being tempted. He was near enough to still be considered, to be “with” his wife, yet far enough away not to hear the conversation.
