CHILD KILLING
"So Joshua . . . utterly destroyed all that breathed, as the Lord God of Israel commanded" (Josh 10:40). The Old Testament claims that God commanded the killing of infants and children to accomplish genocide, group vengeance, and punishment. Imagine if someone killed your child and justified it by saying God told him to do it. See Josh 6:17-21; Deut 2:30- 34; 20:16-17; Isa 14:21; 1 Sam 15:1-3; Num 31:1-2 and 17; Ex 12:29; Gen 7:23; Josh 7:24-25; 2 Kgs 2:23-24.

Vintage Costume Jewelry Owl Pendants.
Since 1987 I have collected over 950 different costume jewelry owl pendants. Almost all were purchased used, initially at California swap meets and thrift stores, later on eBay. Most were mass produced during a fad for owl pendants during the 1970's. Links are provided here to view the entire collection using 33 PicasaWeb Albums. Each item is individually photographed and documented. I hope this will assist collectors of owl jewelry, and provide the general viewer with an appreciation of this episode in popular design.
