'Months' in the Bible

That night -- let thick darkness take it, Let it not be united to days of the year, Into the number of months let it not come.

So I have been caused to inherit months of vanity, And nights of misery they numbered to me.

If determined are his days, The number of his months are with Thee, His limit Thou hast made, And he passeth not over;

For what is his delight in his house after him, And the number of his months cut off?

Who doth make me as in months past, As in the days of God's preserving me?

Thou dost number the months they fulfil? And thou hast known the time of their bringing forth!
