Benjie is a guide writer and trainer with Psalms that Sing. He loves the psalms because they draw us to worship the Lord, and he loves the poetry of the psalms because their beauty turns us to the beauty of the Lord. Benjie spent the 1990's and 2000's working on the Makonde NT translation in northern Mozambique where a fascination with the tonal system of the language led to a doctoral thesis in Bantu linguistics. He has spent the last decade, with his wife Rhoda, serving a variety of translation projects across southern Africa. The Psalms that Sing project brings together Benjie's interest in sound patterns, scripture translation and scripture in use. He also enjoys his grandchildren, construction projects, astronomy and dinghy sailing.
