To ACT WITH INSIGHT, and so to SUCCEED — the two senses are one in Hebrew, because to this literature success is the fruit of understanding, not luck or force. It is the root behind MASKIL ('a contemplative,' a title on several Psalms) and the verb that gave Jacob's crossed hands their meaning ('he crossed his hands SIKKEL — knowingly,' Genesis 48:14). Joshua 1:7-8 promises Joshua he will TASKIL 'wherever you go' — bracketed with TATZLIACH, 'prosper' — and pointedly attaches both to keeping the scroll rather than winning the war. The Bible's own definition of a successful general is a bookish one: prosperity follows from doing what is written. KJV 'then thou shalt have good success.' → first discussed at Joshua 1:7
