'Last Days' in the Bible

And Jacob called unto his sons, and said, Gather yourselves together, that I may tell you that which shall befall you in the last days.

And it shall come to pass in the last days, that the mountain of the LORD's house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it.

But in the last days it shall come to pass, that the mountain of the house of the LORD shall be established on the top of the mountains, and it shall be exalted above the hills; and people shall flow unto it.
