Ramban, on Gen 21:1

“And the Lord visited Sara, as he had promised: and fulfilled what he had spoken.”

“AND THE ETERNAL ‘PAKAD’ (VISITED) SARAH AS HE HAD SAID. That is, by granting her pregnancy. And the Eternal did unto Sarah as He had spoken by granting her the birth of a son..Thus the words of Rashi. But the word pekidah is only an expression of remembrance and attention to the one who is remembered, such as: G-d will surely remember (‘pakod yiphkod’) you; I have surely remembered you; And Samson remembered his wife by [bringing her] a kid. Here, too, the sense of the verse is that the Eternal remembered Sarah, and He did to her as He had spoken. This expression is also found in connection with all barren women who later give birth. Thus, in the case of Rachel: And G-d remembered Rachel; and in the case of Hannah: And G-d remembered her. Similarly, the Rabb is said, “Biblical verses which mention pikdonoth are equivalent to verses which mention Divine remembrances.” is treated as one mentioning remembrance. Thus, Ramban proves that the word pakad in the verse here can mean “remembered,” and not as Rashi explained it as meaning “granting pregnancy.””
