Rav Yehuda said that Rav said: Four must offer thanks to God with a thanks-offering and a special blessing. They are: Seafarers, those who walk in the desert, and one who was ill and recovered, and one who was incarcerated in prison and went out. All of these appear in the verses of a psalm (Psalms 107).
(1) אם על תודה יקריבנו, “If he offers this offering as a thanksgiving offering;” it does require placing his weight on it with his hands before slaughtering, and elevating it, i.e. swinging it, after the slaughtering; (Sifra)
Shlomo Yitzchaki (Hebrew: רבי שלמה יצחקי) 22 February 1040 – 13 July 1105, today generally known by the acronym Rashi (Hebrew: רש"י, RAbbi SHlomo Itzhaki), was a medieval French rabbi and author of a comprehensive commentary on the Talmud and commentary on the Tanakh. Acclaimed for his ability to present the basic meaning of the text in a concise and lucid fashion, Rashi appeals to both learned scholars and beginner students, and his works remain a centerpiece of contemporary Jewish study.

Hezekiah ben Manoah (13th century) or Hezekiah bar Manoah, known as the Chizkuni (Hebrew: חזקוני) was a French rabbi and student.
In memory of his father, who lost his right hand through his steadfastness in the faith, Hezekiah wrote a commentary on the Pentateuch, under the title Ḥazzeḳuni (ca. 1240). It was printed at Venice in 1524. It is based principally upon Rashi, but it uses also about twenty other commentaries, though the author quotes as his sources only Rashi, Dunash ben Labrat, the "Yosippon", and a "Physica" which is mentioned in the Tosafot (to Lev. xii. 2). He is generally cited by the title of his commentary.
