Lo, Children are an heritage of the LORD: and the fruit of the womb is his reward. As arrows are in the hands of a mighty man; so are children of the youth. Happy is the man that hath his quiver full of them: they shall not be ashamed, but they shall speak with the enemies in the gate. 

I pray for them, I pray not for the world, but for them which thou hast given me; for they are thine. And all mine are thine, and thine are mine; and I am glorified in them....these are in the world, and I come to thee, Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are one....Sanctify them through thy truth; thy word is truth.

I kept them in thy name: those that thou gavest me I have kept, and none of them is lost...
