'Surely' in the Bible

And {you must observe them diligently}, for that [is] your wisdom and your insight before the eyes of the people, who will hear all [of] these rules, and they will say, 'Surely this great nation [is] a wise and discerning people.'

And it will happen [that] if you indeed forget Yahweh your God and you go after other gods and you serve them and you bow down before them, I warn you today that you will surely perish.

Surely [just] as the gazelle and the deer is eaten, so [both] the unclean and the clean together may eat it.

Seven days you shall celebrate [your] feast to Yahweh your God at the place Yahweh will choose, for Yahweh your God shall bless you in all of your produce and in all [of] the work of your hand, and you shall surely [be] rejoicing.
