'Opportunity' in the Bible

After this Jesus moved from place to place in Galilee. He would not go about in Judaea, because the Jews were seeking an opportunity to kill Him.

So Jesus replied, "My time has not yet arrived, but you are ready at any opportunity!

Availing herself of the opportunity, Mary took a pound weight of pure spikenard, very costly, and poured it over His feet, and wiped His feet with her hair, so that the house was filled with the fragrance of the perfume.
