Arcana Coelestia # 10615
10615. 'And proclaimed the name of Jehovah' means worship of the Lord springing from the truths and forms of the good of faith and love, and so preparation for reception. This is clear from the meaning of 'proclaiming the name of Jehovah' as worship of the Lord springing from the truths and forms of the good of faith and love. For 'proclaiming' means worship, see 440, 2724, while 'the name of Jehovah' means everything in its entirety by which the Lord is worshipped, thus everything of faith and love, 2724, 6674, 9310, and also the Lord's Divine Human, 2628, 6887, 'Jehovah' in the Word being the Lord, see in the places referred to in 9373. From all this it is evident that 'proclaiming the name of Jehovah' means worship of the Lord springing from the truths and forms of the good of faith and love. The reason why preparation for being received is also meant is that the subject in what follows immediately after this is the Israelite nation who were to be received and for whom Moses prayed.
Matthew 21:9
9
The multitudes who went before him, and who followed kept shouting, "Hosanna to the son of David! Blessed is he who comes in the name of the Lord! Hosanna in the highest!"
