Komentaryong Sumisipi para sa 1 Samuel 7:17

ויבאו מרתה AND THEY CAME TO MARAH — The word מרתה is the same as למרה: a ה at the end of a word (as a suffix) replaces a ל at its beginning (as a prefix). The ת takes the place of the ה which is rooted in (an integral part of) the word מרה; when it is joined with another letter, viz., when it is attached to the ה which is added to the word in place of the ל, the ה of the primary form (the ordinary form of the noun from which longer forms are made by the addition of suffixes) is changed into a ת. Thus, also, every ה which is a root-letter (a letter in the primary form of the noun) is changed into a ת when it is joined to another letter. E. g., we have (Isaiah 27:4) “Fury (חמה) is not in Me”, but (Esther 1:12) “And his fury (חמתו) burned within him”; you see that the ה of the ground-form is changed into a ת because it is to be joined to the ו which has been added. Similar are: (Leviticus 25:44) “Manservant and handmaid (אמה)”, but (Genesis 30:3) “Behold, my handmaid (אמתי) Bilhah”; (Genesis 2:7) “a creature of life (חיה)”, but (Job 33:20) “His life (חיתו) maketh him to abhor bread”; (Judges 4:5) “Between Ramah (רמה) [and Beth-el]”, but (I Samuel 7:17) “And his return was to Ramah (הרמתה)” the latter example being exactly parallel to that in this verse (מרתה - מרה‎).
