Just make sure that the two passages are not "prophecy"
OT saint can speak a prophecy by the inspiration of the Holy Spirit without themself being a prophet/prophetess.
Example = Hannah
And Hannah prayed and said:
“My heart rejoices in the Lord;
My horn is exalted in the Lord.
I smile at my enemies,
Because I rejoice in Your salvation.
2“No one is holy like the Lord,
For
there is none besides You,
Nor
is there any rock like our God.
3“Talk no more so very proudly;
Let no arrogance come from your mouth,
For the Lord
is the God of knowledge;
And by Him actions are weighed.
4“The bows of the mighty men
are broken,
And those who stumbled are girded with strength.
5Those who were full have hired themselves out for bread,
And the hungry have ceased
to hunger.
Even the barren has borne seven,
And she who has many children has become feeble.
6“The Lord kills and makes alive;
He brings down to the grave and brings up.
7The Lord makes poor and makes rich;
He brings low and lifts up.
8He raises the poor from the dust
And lifts the beggar from the ash heap,
To set
them among princes
And make them inherit the throne of glory.
“For the pillars of the earth
are the Lord’s,
And He has set the world upon them.
9He will guard the feet of His saints,
But the wicked shall be silent in darkness.
“For by strength no man shall prevail.
10The adversaries of the Lord shall be broken in pieces;
From heaven He will thunder against them.
The Lord will judge the ends of the earth.
“He will give strength to His king,
And exalt the horn of His anointed.”
