Genesis 3:4

3:4 The serpent said to the woman, “Surely you will not die,

tn The response of the serpent includes the infinitive absolute with a blatant negation equal to saying: “Not – you will surely die” (לֹא מוֹת תִּמֻתען, lomot tÿmutun). The construction makes this emphatic because normally the negative particle precedes the finite verb. The serpent is a liar, denying that there is a penalty for sin (see John 8:44).

sn Surely you will not die. Here the serpent is more aware of what the Lord God said than the woman was; he simply adds a blatant negation to what God said. In the account of Jesus’ temptation Jesus is victorious because he knows the scripture better than Satan (Matt 4:1-11).
