The entire charge must be considered, not just one sentence. Edwards v. Delvero, 139 Ga. App. 880, 881 (2) (229 SE2d 763) (1976). The portion of the charge to which Lawhorn takes exception is followed by an extensive charge on comparative negligence clearly stating that negligence on his part would not prevent recovery if his negligence was less than the defendants'. The jury was instructed that if Lawhorn's failure to exercise ordinary care for his own safety was, however, the proximate cause of his injury, then he could not recover from the defendants. This was a correct statement of the law and did not amount to a charge of the contributory negligence rule. See Crim v. Grantham, 139 Ga. App. 680 (229 SE2d 150) (1976).
