You're quoting Numbers 6:24 way out of context. You're making Christ look uncaring for the suffering of the members of the church in Smyrna (Revelation 2:8-10).
You mis-understand the Promise of being 'Kept' by the LORD.
Numbers 6:24 is the FULL CONTEXT and FULFILLED PROMISE of the GOSPEL
“Whatever I tell you in the dark, speak in the light; and what you hear in the ear, preach on the housetops.
And do not fear those who kill the body but cannot kill the soul. But rather fear Him who is able to destroy both soul and body in hell.
Are not two sparrows sold for a copper coin? And not one of them falls to the ground apart from your Father’s will. But the very hairs of your head are all numbered.
Do not fear therefore; you are of more value than many sparrows.
“I have manifested Your name to the men whom You have given Me out of the world. They were Yours, You gave them to Me, and they have kept Your word. Now they have known that all things which You have given Me are from You. For I have given to them the words which You have given Me; and they have received
them, and have known surely that I came forth from You; and they have believed that You sent Me.
“I pray for them. I do not pray for the world but for those whom You have given Me, for they are Yours. And all Mine are Yours, and Yours are Mine, and I am glorified in them.
Now I am no longer in the world, but these are in the world, and I come to You.
Holy Father, keep through Your name those whom You have given Me, that they may be one as We
are.
While I was with them in the world, I kept them in Your name.
Those whom You gave Me I have kept; and none of them is lost except the son of perdition, that the Scripture might be fulfilled. But now I come to You, and these things I speak in the world, that they may have My joy fulfilled in themselves. I have given them Your word; and the world has hated them because they are not of the world, just as I am not of the world. I do not pray that You should take them out of the world, but that You should keep them from the evil one. They are not of the world, just as I am not of the world.
Sanctify them by Your truth. Your word is truth.
As You sent Me into the world, I also have sent them into the world.
And for their sakes I sanctify Myself, that they also may be sanctified by the truth.
