'Sweet Savor' in the Bible

Then shall ye know that I am the LORD, when their slain men shall be among their idols round about their altars, upon every high hill, on all the tops of the mountains, and under every green tree, and under every thick oak, the place where they offered sweet savor to all their idols.

My provisions also which I gave thee, fine flour, and oil, and honey, with which I fed thee, thou hast even set before them for a sweet savor: and thus it was, saith the Lord GOD.

For when I had brought them into the land, for which I lifted up my hand to give it to them, then they saw every high hill, and all the thick trees, and they offered there their sacrifices, and there they presented the provocation of their offering: there also they made their sweet savor, and poured out there their drink-offerings.

I will accept you with your sweet savor, when I bring you out from the people, and gather you out of the countries in which ye have been scattered; and I will be sanctified in you before the heathen.
