What book in the bible and what verse does it say threetimes that he will not fail you?

Answer 1

None.

In the King James version

the phrase - he will not fail thee - appears three times in the whole bible, in three different verses. Twice in Deuteronomy and once in 1 Chronicles

• 5735 Deu 31:6 Be strong and of a good courage, fear not, nor be afraid of them: for the LORD thy God, he it is that doth go with thee; he will not fail thee, nor forsake thee.
• 5737 Deu 31:8 And the LORD, he it is that doth go before thee; he will be with thee, he will not fail thee, neither forsake thee: fear not, neither be dismayed.
• 11164 1 Chr 28:20 And David said to Solomon his son, Be strong and of good courage, and do it: fear not, nor be dismayed: for the LORD God, even my God, will be with thee; he will not fail thee, nor forsake thee, until thou hast finished all the work for the service of the house of the LORD.

the only other verse with the words - will not fail thee - is this one

• 5857 Jos 1:5 There shall not any man be able to stand before thee all the days of thy life: as I was with Moses, so I will be with thee: I will not fail thee, nor forsake thee.
