'Speak' in the Bible

All things are wearisome;man is unable to speak.The eye is not satisfied by seeingor the ear filled with hearing.

A time to rend, and a time to sew; a time to keep silence, and a time to speak;

Do not be hasty to speak, and do not be impulsive to make a speech before God. God is in heaven and you are on earth, so let your words be few.

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.
