В уста целует, кто отвечает словами верными.
An honest answer is like a kiss on the lips.
Whoever gives an honest answer kisses the lips.
He kisses the lips Who gives a right answer.
An honest answer is like a kiss of friendship.
Every man shall kiss his lips that giveth a right answer.
He who gives a right answer kisses the lips.
He kisseth the lips who giveth a right answer.
