'Complain' in the Bible

As for the men whom Moses sent to spy out the land, and who returned and made all the congregation murmur and complain against him by bringing back a bad report concerning the land,

When their fathers or their brothers come to complain to us, we shall say to them, ‘Give them to us voluntarily, because we did not take a wife for each man of Benjamin in battle, nor did you give wives to them, for that would have made you guilty [of breaking your oath].’”

“Therefore I will not restrain my mouth;I will speak in the anguish of my spirit,I will complain in the bitterness of my soul [O Lord].

“Why do you complain and contend with Me?You have all rebelled (transgressed) against Me,” says the Lord.

You, O Lord are [uncompromisingly] righteous and consistently just when I plead my case with You;Yet let me discuss issues of justice with You:Why has the way of the wicked prospered?Why are those who deal in treachery (deceit) at ease and thriving?

For whenever I speak, I must shout out;I shout violence and destruction,Because the word of the Lord has become to meA reprimand and a mockery and has brought me insult all day long.

Why should any living mortal, or any man,Complain [of punishment] in view of his sins?

And do not murmur [in unwarranted discontent], as some of them did—and were destroyed by the destroyer.

Do not complain against one another, believers, so that you will not be judged [for it]. Look! The Judge is standing right at the door.

These people are [habitual] murmurers, griping and complaining, following after their own desires [controlled by passion]; they speak arrogantly, [pretending admiration and] flattering people to gain an advantage.
