'Months' in the Bible

As for that night, let thick darkness seize upon it: Let it not rejoice among the days of the year; Let it not come into the number of the months.

So am I made to possess months of misery, And wearisome nights are appointed to me.

Seeing his days are determined, The number of his months is with thee, And thou hast appointed his bounds that he cannot pass;

For what careth he for his house after him, When the number of his months is cut off?

Oh that I were as in the months of old, As in the days when God watched over me;

Canst thou number the months that they fulfil? Or knowest thou the time when they bring forth?
