'Speak' in the Bible

All these things are wearying; a man is not able to speak, the eye is not satisfied by seeing, nor filled is the ear from hearing.

A time to rend, And a time to sew. A time to be silent, And a time to speak.

Also to all the words that they speak give not thy heart, that thou hear not thy servant reviling thee.

then I considered all the work of God, that man is not able to find out the work that hath been done under the sun, because though man labour to seek, yet he doth not find; and even though the wise man speak of knowing he is not able to find.
