'Surely' in the Bible

After a little while those who stood by came and said to Peter, "Surely you are also one of them, for your speech makes you known."

They began to be sorrowful, and to ask him one by one, "Surely not I?" And another said, "Surely not I?"

Jesus therefore said to Peter, "Put the sword into its sheath. The cup which the Father has given me, shall I not surely drink it?"

I have surely seen the affliction of my people that is in Egypt, and have heard their groaning. I have come down to deliver them. Now come, I will send you into Egypt.'

saying, "Surely blessing I will bless you, and multiplying I will multiply you."

But these, as unreasoning creatures, born natural animals to be taken and destroyed, speaking evil in matters about which they are ignorant, will in their destroying surely be destroyed,
