'Months' in the Bible

That night--let the thick dark take it; let it not have joy among the days of the year; let it not come into the number of the months.

So I have for my heritage months of pain to no purpose, and nights of weariness are given to me.

If his days are ordered, and you have knowledge of the number of his months, having given him a fixed limit past which he may not go;

For what interest has he in his house after him, when the number of his months is ended?

If only I might again be as I was in the months which are past, in the days when God was watching over me!

Is the number of their months fixed by you? or is the time when they give birth ordered by you?
