"We" here are Jews and the author here obvously is Nehemiah. Ammonite are enemies of Jews. 1st point in verse 1-3, expect there is speculation. A leader should be an example. Paul the apostle said; "When we are cursed, we are blessed. When we are persecuted, we endure." Jesus promised us you will have rewards from heaven, when you are persecuted in being righteous. When we are weak, He is strong.
One of the tools from the enemy is you will be mocked. In verse 4, we can see Nehemiah's reaction that he turn to God and he did not fight back what they have done to him. Jesus want us to love our neighbor and don't treat them as enemy.
Ephesians 6:11-17 11 Put on the full armor of God, so that you can take your stand against the devil’s schemes. 12For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. 13 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. 14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, 15and with your feet fitted with the readiness that comes from the gospel of peace. 16 In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. 17 Take the helmet of salvation and the sword of the Spirit, which is the word of God.
As for us, when we do the work of God make sure you do it wholeheartedly.
