'Surely' in the Bible

I will wreck both the winter house and the summer house, and the ivory houses will fall. These palaces will surely fall," declares the LORD.

but don't seek Bethel. Don't go to Gilgal, and don't pass over to Beer-sheba. Because Gilgal will surely go into captivity, and Bethel will come to nothing.

because Amos is saying this: "By the sword will Jeroboam die, and Israel will surely go into exile far from her homeland.'"

"Therefore this is what the LORD says: "Your wife will become a whore in the city, and your sons and daughters will die by the sword. Your land will be divided and apportioned, and you will die in a foreign land. Israel will surely go into exile, far from its homeland."'"

Surely the land will tremble because of this, won't it? And all who live in it will mourn, won't they? The entire land will swell up like a flooded river. It will be stirred up and then will sink like the river of Egypt.

I will surely restore my people Israel; they will rebuild the ruined cities and inhabit them. They will plant vineyards and drink the wine from them. They will plant gardens and eat the fruit from them.
