Quite often there is a difference between Hebrew numbering and LXX numbering. For example Psalm 9-10 are one psalm in LXX and a latter one in the 140s i think is split into two. Malachi in the henew has a longer chapter 3 and no chapter 4. Generally we follow the Hebrew number in the english Bible but not always. Catholics traditionally always followed the LXX numbering for the Psalms but now a days that is almost never the case except I noticed many catholic prayer books still use the LXX numbering. As you can see the difference below.
Hos. 1:9 (NRSVS) Then the LORD said, “Name him Lo-ammi, for you are not my people and I am not your God.”
Hos. 1:10 (NRSVS) ¶ Yet the number of the people of Israel shall be like the sand of the sea, which can be neither measured nor numbered; and in the place where it was said to them, “You are not my people,” it shall be said to them, “Children of the living God.”
Hos. 1:11 (NRSVS) The people of Judah and the people of Israel shall be gathered together, and they shall appoint for themselves one head; and they shall take possession of the land, for great shall be the day of Jezreel.
Hos. 2:1 (NRSVS) ¶ Say to your brother, Ammi, and to your sister, Ruhamah.
Hos. 2:2 (NRSVS)
Plead with your mother, plead—
for she is not my wife,
and I am not her husband—
that she put away her whoring from her face,
and her adultery from between her breasts,
Hos. 2:3 (NRSVS) or I will strip her naked
and expose her as in the day she was born,
and make her like a wilderness,
and turn her into a parched land,
and kill her with thirst.
