'Strengthened' in the Bible

Then the one (Gabriel) whose appearance was like that of a man touched me again, and he strengthened me.

He said, “O man, highly regarded and greatly beloved, do not be afraid. Peace be to you; take courage and be strong.” Now when he had spoken to me, I was strengthened and said, “Let my lord speak, for you have strengthened me.”

After some years the Syrian king of the North and the Egyptian king of the South will make an alliance; the daughter (Berenice) of the king of the South will come to the king of the North to make an equitable and peaceful agreement (marriage); but she will not retain the power of her position, nor will he retain his power. She will be handed over with her attendants and her father as well as he who supported her in those times.
