Proverbs 27:1: Boast not thyself of to morrow; for thou knowest not what a day may bring forth. [to...: Heb. to morrow day]
Contradiction with Jeremiah 17:5
This verse states that reliance on man is cursed, contrasting with 1 Kings 1:48, where David blesses God for setting Solomon on the throne, which involved human actions.
Jeremiah 17:5: Thus saith the LORD; Cursed [be] the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD.
