We want others to get a blessing. 
Genesis 12
1 Now the L-RD had said to Abram:
        “Get out of your country, 
         From your family 
         And from your father’s house, 
         To a land that I will show you. 
2 I will make you a great nation;
    I will bless you 
And make your name great; 
   And you shall be a blessing. 
3 I will bless those who bless you,
    And I will curse him who curses you; 
    And in you all the families of the earth shall be blessed.”

Because we want others to know that we owe the Jewish people a debt for the blessings that we have received through them.
Romans 9
3 For I could wish that I myself were accursed from Christ for my brethren, my countrymen according to the flesh, 4 who are Israelites, to whom pertain the adoption, the glory, the covenants, the giving of the law, the service of God, and the promises; 5 of whom are the fathers and from whom, according to the flesh, Christ came, who is over all, the eternally blessed God. Amen.

With others we can help in facilitating the regathering of Israel. 
“I will take the children of Israel from among the nations, wherever they have gone, and will gather them from every side and bring them into their own land; 22 and I will make them one nation in the land, on the mountains of Israel; and one king shall be king over them all”-Ezekiel 37:21-22

We want others to come alongside us and seek the good of Israel through prayer and comfort. 
In Isaiah chapter 40 God speaks; “Comfort, comfort my people says you God. Speak tenderly to Jerusalem and cry to her that h er warfare is ended, that her iniquity is pardoned, that she has received from the Lord’s hand double for all her sins.” This is a call for Christians to comfort the Jewish people.  Isaiah also envisions that in their regathering, the leaders of the nations would help the Jewish people and nurture them: “Thus says the Lord God; ‘Behold I will lift up my hand to the nations, and raise my signal to the peoples; and they shall bring your sons in their bosom, and your daughters shall be carried on their shoulders. Kings shall be your foster brothers and their queens your nursing mothers” (Isaiah 49:22-23). God says that the Gentiles will nurture and assist the Jewish people in their reentry to their land.

Psalm 122
1 I was glad when they said to me,
   “Let us go into the house of the LORD.”
 2 Our feet have been standing
   Within your gates, O Jerusalem! 
      
 3 Jerusalem is built
    As a city that is compact together,
 4 Where the tribes go up,
    The tribes of the LORD, 
    To the Testimony of Israel, 
    To give thanks to the name of the LORD.
 5 For thrones are set there for judgment,
    The thrones of the house of David. 
         
 6 Pray for the peace of Jerusalem:
     “May they prosper who love you.
 7 Peace be within your walls,
    Prosperity within your palaces.”
 8 For the sake of my brethren and companions,
    I will now say, “Peace be within you.”
 9 Because of the house of the LORD our God
    I will seek your good.

25 But now I am going to Jerusalem to minister to the saints. 26 For it pleased those from Macedonia and Achaia to make a certain contribution for the poor among the saints who are in Jerusalem. 27 It pleased them indeed, and they are their debtors. For if the Gentiles have been partakers of their spiritual things, their duty is also to minister to them in material things.-Romans 9:25-27
