Some modern Jews claim that seeking the prayers and intercession of Rachel is an ancient tradition.

More than a hundred years after the exile of the North, Jeremiah had a vision of Rachel still mourning, still grieving for her lost children. Moreover, he realized that her mourning served as an effective intercession, for God promised to reward her efforts and return her children (Jer 31:15–21). After the biblical period, “Mother Rachel” continued to be celebrated as a powerful intercessor for the people of Israel.

According to the Jewish tradition, the matriarch Rachel has always cried for her people whenever the Jewish people needed her. Jacob reportedly buried Rachel in Bethlehem, instead of in the Tomb of Patriarchs in Hebron because he foresaw that his descendants would need her prayers en route to exile in Babylonia.
Is this practice admonished anywhere in the New Testament?
