[25:28] 1 tn Heb “whose spirit lacks restraint” (ASV similar). A person whose spirit (רוּחַ, ruakh) “lacks restraint” is one who is given to outbursts of passion, who lacks self-control (cf. NIV, NRSV, CEV, NLT). This person has no natural defenses but reveals his true nature all the time. The proverb is stating that without self-control a person is vulnerable, like a city without defenses.
