Commentators explain that the name 'Jehovah' (translated as 'LORD' in all caps) is the personal name of God, directly related to 'I AM' from the previous verse. It signifies His eternal, self-existent, and unchanging nature. While 'I AM' expresses His being from a first-person perspective, 'Jehovah' is the third-person form, becoming the primary name by which His people would know and remember Him.
