When Moab appears at her high place, she only wears herself out; when she goes to her shrine to pray, it is to no avail.
NIV
It shall be that when Moab presents himself, when he wearies himself [worshiping] on the high place [of idolatry], he will come to his sanctuary [of Chemosh, god of Moab], but he will not prevail. [Then will he be ashamed of his god.][Jer. 48:13.]AMP
And it shall come to pass, when it is seen that Moab is weary on the high place, that he shall come to his sanctuary to pray; but he shall not prevail.
KJV
I will give Moab along with the Ammonites to the people of the East as a possession, so that the Ammonites will not be remembered among the nations;
NIV
I will give it along with the children of Ammon to the people of the East for a possession, that it and the children of Ammon may not be [any more seriously] remembered among the nations.
AMP
Unto the men of the east with the Ammonites, and will give them in possession, that the Ammonites may not be remembered among the nations.
KJV
"And I will inflict punishment on Moab. Then they will know that I am the LORD."
NIV
And I will execute judgments and punishments upon Moab, and they shall know (understand and realize) that I am the Lord [the Sovereign Ruler, Who calls forth loyalty and obedient service]. [Isa. 15, 16; Jer. 48; Amos 2:1-3; Zeph. 2:8-11.]AMP
And I will execute judgments upon Moab; and they shall know that I am the LORD.
