פירוש על שמואל א 1:13

Eili thought she was drunk. Because they were not accustomed to praying silently.

And Channah: But, "Channah was praying in her heart" - meaning to say, in a whisper, as if she was speaking to her heart, so it was not audible to Eli.

Spoke in her heart: It is like its translation [in Targum Yonatan], "she prayed in her heart." Meaning to say, she concentrated [with] her heart in prayer.

And he thought she was drunk: For this is the way of a drunkard to move his lips, but there is 'no speech and no words.'
