War in the Word represents the combat of temptation when good loves are assaulted by evil loves or false ideas. The evil that attacks comes from one of the many societies of hell, and it operates by arousing a selfish love in our mind that is contrary to what we know is right. Then our selfish love attacks the love that nourishes the wish to be a good person, and there is war in our minds. This is represented by wars that the children of Israel fought in and around the land of Canaan, of which there is a long history in the old testament. The selfish loves abound in our minds from our heredity, and the good loves come along with our conscience as it develops. If we had no conscience we couldn't be tempted; we would immediately follow the wishes of our selfishness and give in. But then the end result is that we are in slavery to the hells and will do whatever they want.

1788. That 'a shield' means protection against evils and falsities which is able to be trusted is clear without explanation, for repeated usage has made the saying familiar that 'Jehovah is a shield and buckler'. But what is meant specifically by 'a shield' becomes clear from the Word, namely that in reference to the Lord it means protection, and in reference to man trust in the Lord's protection. As 'war' means temptations, as shown in 1664, so every implement of war means some specific aspect of temptation and of defence against evils and falsities, that is, against the devil's crew who bring temptation about and do the tempting. Consequently 'shield' means one thing, 'buckler' another, 'target' another, 'helmet' another, 'spear' and also 'javelin' another, 'sword' another, 'bow and arrows' another, and 'breastplate' another. In the Lord's Divine mercy these will be dealt with individually later on.

[2] The reason why in reference to the Lord 'a shield' means protection against evils and falsities, and in reference to man trust in the Lord, is that it was a means of protection to the breast, and 'the breast' meant good and truth - good because the heart is within it, and truth because the lungs are within it. That 'a shield' has this meaning is clear in David,

Blessed be Jehovah my rock who trains my hands for battle and my fingers for war; my mercy, and my fortress, my stronghold and my deliverer, my shield and He in whom I trust. Psalms 144:1-2.

Here 'battle' and 'war' are the battle and war of temptations, and in the internal sense, of the Lord's temptations. 'A shield' in reference to Jehovah is protection, and in reference to man trust, as is quite evident.

[3] In the same author,

O Israel, trust in Jehovah! He is their help and their shield. O house of Aaron, trust in Jehovah! He is their help and their shield. You who fear Jehovah, trust in Jehovah! He is their help and their shield. Psalms 115:9-11.

Here the meaning is similar. In the same author,

Jehovah is my fortress, my God in whom I will trust. He will cover you with His wing, and under His wings will you put your trust. His truth is a buckler and target. Psalms 91:2, 4.

Here 'buckler and target' stands for protection against falsities.

[4] In the same author,

Jehovah is my rock (petra) and my fortress, and my deliverer, my God, my rock (rupee) in whom I trust, my shield and the horn of my salvation. Jehovah is a shield for all who trust in Him. Psalms 18:2, 30.

Here the meaning is similar. In the same author,

You who test the heart ¹ and reins, a righteous God; my shield is with God who saves the upright in heart. Isaiah 7:9, 10.

You have given me the shield of Your salvation, and Your right hand will support me. Psalms 18:35.

Your blessings, O Israel! Who is like you, a people saved in Jehovah, the shield of your help, and One who is the sword of your excellency! Your enemies will be mistaken in regard to you. Deuteronomy 33:29.

'Shield' stands for protection.

[6] Even as weapons of war are attributed to those engaged in conflicts brought about by temptations, so also are the same weapons attributed to the enemies assailing and tempting. When attributed to the latter, the contrary meanings held by those weapons is being expressed; for example, 'a shield' in this case means the evils and falsities from which those enemies fight, and which they defend, and in which they put their trust, as in Jeremiah,

Prepare shield and buckler, and advance for battle. Harness the horses, and mount, O horsemen! Take up your stations in your helmets, polish your lances, put on your breastplates. Jeremiah 46:3-4.

There are many more examples besides these.
