- Psalm 137 (Wikipedia)
Psalm 137 is the 137th psalm of the Book of Psalms, beginning in English in the King James Version: “By the rivers of Babylon, there we sat down”. The Book of Psalms is part of the third section of the Hebrew Bible, and a book of the Christian Old Testament. In the slightly different numbering system used in the Greek Septuagint and Latin Vulgate translations of the Bible, this psalm is Psalm 136. In Latin, it is known by the incipit, “Super flumina Babylonis”. The psalm is a communal lament about remembering Zion, and yearning for Jerusalem while dwelling in exile during the Babylonian captivity.
- Selenium (Wikipedia)
Selenium is a chemical element; it has the symbol Se and atomic number 34. It has various physical appearances, including a brick-red powder, a vitreous black solid, and a grey metallic-looking form. It seldom occurs in this elemental state or as pure ore compounds in Earth’s crust. Selenium (from Ancient Greek σελήνη (selḗnē) ‘moon’) was discovered in 1817 by Jöns Jacob Berzelius, who noted the similarity of the new element to the previously discovered tellurium (named for the Earth).
