'Seek' in the Bible

Now, they having departed, behold, an angel of the Lord appears in a dream to Joseph, saying, Arise, take to thee the little child and his mother, and flee into Egypt, and be there until I shall tell thee; for Herod will seek the little child to destroy it.

for all these things the nations seek after; for your heavenly Father knows that ye have need of all these things.

But seek ye first the kingdom of God and his righteousness, and all these things shall be added unto you.

Ask, and it shall be given to you. Seek, and ye shall find. Knock, and it shall be opened to you.

What think ye? If a certain man should have a hundred sheep, and one of them be gone astray, does he not, leaving the ninety and nine on the mountains, go and seek the one that has gone astray?

And the angel answering said to the women, Fear not ye, for I know that ye seek Jesus the crucified one.
