פּירוש אויף רות 1:15

See, your sister-in-law has gone back. In this [word], the accent is at the beginning [on the first syllable] under the shin, because it is in the past tense. [But,] “and in the morning she would return,”²²Megillas Esther 2:14. the accent is at the end [on the last syllable], on the bais, because it is in the present tense, and so it is in all similar cases.²³See Rashi in Bereishis 29:6.

"Return with your sister-in-law to her people and her gods" — this is a sign that she had already separated from her god before this.

"Do not urge me": The meaning is to pacify, and it is always connected with the letter "bet" (ב), as in "and entreat Ephron for me" (Genesis 23:8). It is not an unusual word, just that "I will not urge a person" and in its place, I will explain it.
