The verses before and after Hebrews 11:33 make clear that different promises are being discussed:
32 And what more shall I say? For the time would fail me to tell of Gideon and Barak and Samson and Jephthah, also of David and Samuel and the prophets: 33 who through faith subdued kingdoms, worked righteousness, obtained promises, stopped the mouths of lions, 34 quenched the violence of fire, escaped the edge of the sword, out of weakness were made strong, became valiant in battle, turned to flight the armies of the aliens. 35 Women received their dead raised to life again. -Hebrews 11:32-34 (NKJV)
A few men are named, followed by "the prophets" at the end of the list. Specific promises were made to several of these people.
To Gideon was promised military victory:
11 Now the Angel of the Lord came and sat under the terebinth tree which was in Ophrah, which belonged to Joash the Abiezrite, while his son Gideon threshed wheat in the winepress, in order to hide it from the Midianites. 12 And the Angel of the Lord appeared to him, and said to him, “The Lord is with you, you mighty man of valor!”
13 Gideon said to Him, “O my lord, if the Lord is with us, why then has all this happened to us? And where are all His miracles which our fathers told us about, saying, ‘Did not the Lord bring us up from Egypt?’ But now the Lord has forsaken us and delivered us into the hands of the Midianites.”
14 Then the Lord turned to him and said, “Go in this might of yours, and you shall save Israel from the hand of the Midianites. Have I not sent you?”
15 So he said to Him, “O my Lord, how can I save Israel? Indeed my clan is the weakest in Manasseh, and I am the least in my father’s house.”
16 And the Lord said to him, “Surely I will be with you, and you shall defeat the Midianites as one man.” -Judges 6:11-16 (NKJV)
Gideon obtained specific promises of victory over the Midianites.
Jeremiah, one of the prophets, was promised deliverance:
4 Then the word of the Lord came to me, saying:
5 “Before I formed you in the womb I knew you;
Before you were born I sanctified you;
I ordained you a prophet to the nations.”
6 Then said I:
“Ah, Lord God!
Behold, I cannot speak, for I am a youth.”
7 But the Lord said to me:
“Do not say, ‘I am a youth,’
For you shall go to all to whom I send you,
And whatever I command you, you shall speak.
8 Do not be afraid of their faces,
For I am with you to deliver you,” says the Lord. -Jeremiah 1:4-8 (NKJV
20 “And I will make you to this people a fortified bronze wall;
And they will fight against you,
But they shall not prevail against you;
For I am with you to save you
And deliver you,” says the Lord.
21 “I will deliver you from the hand of the wicked,
And I will redeem you from the grip of the terrible.” -Jeremiah 15:20-21 (NKJV)
Jeremiah was delivered several times from the hands of the wicked that were trying to kill him (e.g. Jeremiah 26 and Jeremiah 38). Jeremiah obtained specific promises of deliverance.
The promises spoken of in Hebrews 11:33 are not the same promises referred to in Hebrews 11:13. The promises spoken of in Hebrews 11:13 refer to "the city which has foundations, whose builder and maker is God."
8 By faith Abraham obeyed when he was called to go out to the place which he would receive as an inheritance. And he went out, not knowing where he was going. 9 By faith he dwelt in the land of promise as in a foreign country, dwelling in tents with Isaac and Jacob, the heirs with him of the same promise; 10 for he waited for the city which has foundations, whose builder and maker is God. -Hebrews 11:8-10 (NKJV)
The promises not yet received were of a city built by God, and also of a heavenly homeland:
13 These all died in faith, not having received the promises, but having seen them afar off were assured of them, embraced them and confessed that they were strangers and pilgrims on the earth. 14 For those who say such things declare plainly that they seek a homeland. 15 And truly if they had called to mind that country from which they had come out, they would have had opportunity to return. 16 But now they desire a better, that is, a heavenly country. Therefore God is not ashamed to be called their God, for He has prepared a city for them.
