Yahweh would remember the just righteous ones (Mal 3:16-3:16)

“Then those who revered Yahweh

Spoke with one another.

Yahweh took notice.

Yahweh listened.

A book of remembrance

Was written

Before him

Of those

Who revered Yahweh,

Of those

Who thought on his name.”

However, there was a group of Israelites who revered Yahweh.  They spoke among themselves.  Yahweh saw and listened to this, as he took notice of what was going on.  There was a book of remembrance, where all the names of those who revered Yahweh and his name were written down.  This is where we get the idea that someone is keeping track of our lives in a book.
