Jacob Keest was a deacon of the Flemish Mennonite congregation at Franeker, Dutch province of Friesland, who in 1586 opposed Elder Thomas Byntgens and soon became the principal leader of the Contra-Huiskoopers, Byntgens being the leader of the Huiskoopers. Jacob Keest is thought to be identical with Jacques Outerman, who about 1600 was a well-known preacher at Haarlem. Perhaps earlier traces of Jacob Keest can be found if we assume that he is the same person as the Jacob Keest mentioned by Verheyden (Courtrai-Bruxelles, 20) who in 1553 was a cloth merchant living at Kortrijk (Courtrai) in Flanders, Belgium, near the (Cloth) Hall, and who was suspected as to his religion.
