'Days' in the Bible

Thus says the Lord of hosts, ‘If it is difficult in the eyes of the remnant of this people in those days [in which this comes to pass], will it also be difficult in My sight?’ declares the Lord of hosts.

“Thus says the Lord of hosts, ‘Let your hands be strong, you who in these days hear these words from the mouths of the prophets who, on the day that the foundation of the house of the Lord of hosts was laid, foretold that the temple might be rebuilt.

For before those days there were no wages for man or animal; nor was there any peace or success for him who went out or came in because of his enemies, for I set all men against one another.

But now [in this time since you began to build] I will not treat the remnant of this people as in the former days,’ declares the Lord of hosts.

so I have again planned in these days to do good to Jerusalem and to the house of Judah. Do not fear!

Thus says the Lord of hosts, ‘In those days ten men [as representatives] from all the nations will grasp the robe of a Jew, saying, “Let us go with you, for we have heard that God is with you.”’”

You will flee by the valley of My mountains, for the valley of the mountains will reach to Azel; and you will flee just as you fled from the earthquake in the days of Uzziah king of Judah. Then the Lord my God will come, and all the holy ones (believers, angels) with Him.
