'Completely' in the Bible

They have said in their heart, "We will completely oppress them." They burned all the meeting places of God in the land.

Let sinners perish completely from the earth, and [the] wicked {not remain alive}. Bless Yahweh, O my soul. Praise Yah.

For [there is] not a word [yet] on my tongue, [but] behold, O Yahweh, you know it completely.
