'Truly' in the Bible

The grapevine is shriveled and the fig tree is withered, along with the pomegranate tree, the palm tree, the apple tree and all of the cultivated trees. Truly, joy has evaporated from Adam's children."

The LORD will shout in the presence of his forces, because his encampment is very great; for powerful is he who carries out his message. Truly the Day of the LORD is great, and very terrifying. Who will be able to survive it?"

"And truly you will know that I am the LORD your God, dwelling in Zion, my holy mountain. Then Jerusalem will be holy, and no foreigners will invade her again.
