In Isaiah 40:9 and Psalm 69:35, this signifies the doctrine of love of the Lord and the neighbor in its entirety as well as the doctrine of the celestial church. (Apocalypse Explained 342, 850[5])

'Word,' as in Isaiah 9:8, signifies the doctrine of internal and external worship. 'Word,' as in Psalms 119:6-17, stands for doctrine in general.

'The Word,' as in Psalms 147:18, signifies divine good united with divine truth.

The whole Word is nothing but the doctrine of love towards the Lord, and love towards our neighbor, as in Matthew 22.
